Based on the cost and frequency of needing to update the maps into the car, how many of you would buy the technology package (ZTP) again? I know there is the issue of resale value with the car but it seems the car navigation system will become outdated faster than just getting a new smartphone that has navigation, traffic, and driving directions built in (Android and iOS) and has free updates. You can even cache an area on the phone ahead of time if you know there will be no signal. What would be nice is to have DLNA in the car OS to allow the phone to project its version of maps onto the display.
Just asking because I'm trying to justify the addition of ZTP to my potential build.
