Cartrack - do not install these units!
We chose Cartrack in addition to our insurance coverage and subsequently Cartrack fitted their tracking units with DVR systems for video recording. This is where our problems started as we then suffered constant berry drains on various vehicles with costly replacement of damaged batteries. Even informing Cartrack of this always has a negative response towards us being the customer "that if we had tampered with their equipment the repairs would be for our account" Why would we tamper??? The last nail in the coffin so to speak was when one of our employees was involved in an accident with another car. Subsequently I tried to download the video footage which was of course not possible. A Cartrack technician was sent out and the HDD replaced so that Cartrack can see if they can retrieve the footage from the replaced HDD - to date nothing. During the replacement their technician informs us he "found two other live systems"  How is this possible if only Cartrack techs worked on the vehicle? 

I then requested that Cartrack remove their systems as it clearly does not work. This has been ongoing for weeks now with us as the customer being bluntly ignored.  In the interim the driver of the driver of the other vehicle has sent their bill for repairs and we have no video footage to prove they caused the accident. Disgusting and poor service.
