s vehicle 24 includes a telematic control unit 26 and a radio 28 . as shown in fig2 , the telematic control unit 26 includes a processor 30 , a built - in global positioning system ( gps ) unit 32 , a wireless communication module 34 , a vehicle information component 36 , and a user interface 38 . vehicle information component 36 extracts information related to the vehicle &# 39 ; s sensory status , such as engine specification , door lock / unlock status , and airbag deployment requirements from vehicle 24 . user interface 38 includes one or more of a microphone , a speaker , a display , such as a touch sensitive screen , and user interface buttons . main system 22 generates interactive content for use by the user at the vehicle . the interactive content can include a wide variety of information including , for example , product information . the main system previously receives the interactive content from associated business server 20 . telematic control unit 26 sends the interactive content via gateway 14 . wireless communication module 34 wirelessly receives the interactive content from gateway 14 . processor 30 presents the received interactive content to the motorist via user interface 38 . the content is presented visually , audibly , or using a combination of both . using telematic control unit 26 , the user can select from the offered content ( products or services ) directly related to the broadcasted radio content . the interactive content is related to broadcasted radio content and the specific circumstances of the user . main system 22 obtains information related to the broadcasted radio content , such as broadcast time schedule , from the business system . the main system determines what interactive content to send based on the radio station the motorist is listening to , and where to send the interactive content based on the vehicle &# 39 ; s location . this information is obtained from the vehicle &# 39 ; s telematic control unit . likewise , main system 22 obtains financial account information from the user , which in turn is used to authorize purchases . the resulting system provides the user with a variety of options with respect to making purchases based on the interactive content presented over the radio . for example , if a user hears a song on the radio and requests to purchase that cd , the user can request to purchase one and have the cost charged to his / her account number and delivered to an address on file . alternatively , the user could authorize purchase of the cd but , desiring to pick it up as soon as possible , could have the transaction completed at the nearest music store , so that the purchased product is waiting for pickup . in still another embodiment , the user drives vehicle 24 to a fast download site . the download site ( i . e ., hot spot ) is a location that has enhanced data channel communication to vehicle 24 , thereby allowing for a greater amount of data to be downloaded in a shorter period of time . the hot spot includes a wireless communications component capable of communicating wireless data transmission content at a much greater capacity to a vehicle in close proximity . the telematic control unit &# 39 ; s wireless communication module 34 is capable of sending and receiving both voice and data wirelessly to gateway 14 . the wireless gateway is in direct communication with network 12 . when a motorist or passenger makes a selection related to the presented interactive content , wireless communication module 34 sends a request in the form of a message to process a transaction to wireless gateway 14 , such as a request to purchase an item . the wireless gateway directs the request to main system 22 for processing . the wireless gateway facilitates communication between a wireless network ( e . g ., cellular telephone network ) and other networks . bridges , routers , and switches are components of others systems that may be used to connect different networks . main system 22 determines if the user message is associated with a bank transaction , a business transaction , or both . the main system communicates with bank server 18 for completing a bank transaction , such as verifying a user &# 39 ; s credit card , account information and address . once the transaction is completed , main system 22 sends confirmation back to vehicle 24 via wireless gateway 14 . in one example , if the user selects to purchase an item ( e . g ., a sub sandwich ) that is included in a commercial advertisement radio broadcast , the gps receiver sends the user &# 39 ; s current vehicle location and trajectory information to main system 22 via network 12 . the vehicle location is checked against the business transaction server to locate the nearest establishment associated with the broadcasted content . furthermore , a timestamp is used in determining the estimated time of arrival ( eta ) with respect to that establishment . a confirmation of the transaction and the location of the establishment are sent back to the user interface . referring now to fig3 , an illustrative routine for the operation of telematic control unit 26 utilizing main system 22 to send and retrieve information relating to monetary transactions and radio broadcast content via the internet is described . first , at block 60 , the telematic control unit 26 receives the radio broadcast signal . typically , the radio broadcast signal originates from a radio tower in analog form and is transmitted to a radio receiver in vehicle 24 . at block 62 , information related to the radio broadcast is determined . in this step , the main system determines the radio broadcast channel information associated with the vehicle . this may be accomplished by sending radio broadcast channel information from the telematic control unit to the main system . the main system uses radio broadcast channel information to determine what information is related to the radio broadcast of interest to the vehicle user . at block 64 , the main system 22 sends information content related to the radio broadcast to telematic control unit 26 via gateway 14 . the information content is a function of what the radio station is broadcasting and the businesses that are participating in the system . next , at block 66 , if the user makes a selection pertaining to any of the information content presented by telematic control unit 26 , the telematic control unit sends information related to the user &# 39 ; s selection as well as vehicle information to main system 22 via a wireless communication link . the information sent from the telematic control unit to the main system can include vehicle location and trajectory , a request to perform a transaction , or a request for more information concerning broadcast content . the wireless communication link may include a cellular station , a satellite dish , or other wireless communication system , which provides access to network 12 . at block 68 , main system 22 searches a database to process the request for more information related to the broadcasted content , or to process the request to perform a monetary transaction . in an alternative embodiment , main system 22 can send information about content to be broadcast in the near future , for example , the title of songs that will be broadcast in the next 15 minutes . this information is sent to the telematic control unit &# 39 ; s cache memory to be displayed in a timely fashion . the telematic control unit discards the cache information in the event the user switches radio stations or frequencies . at block 70 , main system 22 retrieves textual or audio information related to the processed request and returns the results to telematic control unit 26 . at block 72 , the telematic control unit presents the received results , which includes a digest of information about the broadcast requested , confirmation results of any monetary transaction , and directions to a requested site or any other information generated by main system 22 . the digest of information can be displayed on the telematic control unit &# 39 ; s display , or the vehicle radio &# 39 ; s display . the telematic control unit can also present results aurally . in one example , a user in a vehicle listening to music wishes to request more information about the music , or wishes to purchase a cd of the playing music . for instance , the song “ candy ” is playing on the radio . the display on telematic control unit 26 shows “ candy everybody . . . ” after related information is received from main system 22 via the network and the gateway . the user can request more information , by either pressing a button or uttering a keyword or phrase . for example , the user says “ song information .” the microphone receives these words , after which telematic control unit 26 digitizes the received words and delivers them to main system 22 for voice processing . alternatively , the content may have already been downloaded and is simply played to the user . the telematic control unit either responds aurally and / or displays the textual information : “ candy everybody wants by 10 , 000 maniacs , cd $ 7 . 00 , in stock ” that is received from main system 22 . the user can further request to purchase the cd by either pressing a button or uttering a keyword . once the user says “ purchase ,” the telematic control unit sends a request to the server via the network . the server processes the request to purchase the cd by contacting the cd production company using the user &# 39 ; s financial service company to complete the transaction . the telematic control unit verbally responds or displays a confirmation , for example : “ your confirmation code is cm1234 . the cd will be sent to your address on file .” in another example , a user listens to an advertisement for a sandwich restaurant , the user can purchase a sub from the sandwich restaurant by either pressing a button or uttering a keyword , for example : “ buy jumbo club .” the request is sent to the server via the internet , and telematic control unit 26 responds or displays : “ the nearest subway location is about 0 . 7 miles off exit 167 and has a drive - through . would you like to buy your club sandwich at that location for $ 1 . 99 ?” the user can then purchase the sandwich , by either pressing a button or uttering “ purchase .” once the user selects to purchase the sandwich , a request is sent to the server via network 12 , which processes the request and returns an order number . the telematic control unit displays or responds : “ your order number is 57 .” continuing with fig3 , at block 72 , telematic control unit 26 displays results of a request or a confirmation of a monetary transaction . at block 74 , main system 22 determines if the user selected a request for more information or a monetary transaction . as previously described , a user can request for more information or a monetary transaction related to the broadcast by either pressing a button or uttering a keyword or phrase . if it is determined that a user selected a request for a transaction ( whether monetary or for more information ) at block 74 , the request is sent over a wireless communication link to main system 22 for processing . if , at block 74 , it is determined the user did not select to process any requests , then the logic continues to decision block 76 to determine if the user has turned off the telematic control unit . if it is determined that the user wishes to continue receiving radio broadcast signals , then the logic returns to the beginning , where another radio broadcast signal is received and processed accordingly . if , at block 76 , it is determined the user has turned off the telematic control unit , the process ends at block 78 . in an alternate embodiment , the vehicle is equipped with a tv receiver and the broadcast content is television . in this embodiment , the vehicle user or passenger can interact with the system in a similar manner as outlined above . in still another embodiment , the processor in the vehicle performs voice recognition processing of the voice request to generate textual representation of the recorded request . the processor in the vehicle then sends the textual representation of the recorded request to the server . while the preferred embodiment of the invention has been illustrated and described , as noted above , many changes can be made without departing from the spirit and scope of the invention . accordingly , the scope of the invention is not limited by the disclosure of the preferred embodiment . instead , the invention should be determined entirely by reference to the claims that follow .
