Edit: somehow it has gotten even worse. Maps is always searching for a GPS signal, unplug my phone, it finds one, plug it back in and it can't find it. Absolutely useless now. When it works, it is great, unfortunately this is less than 50% of the times I plug it in. To fix it, I have to turn the car ignition off, reboot the phone and hope it works, it not retry then process again. Extremely frustrating when you want to just plug in and go.
