OMG, I am so glad I got the 8 inch screen and NO friggin Nav. Why do people still order built in GPS? Every one I've had since my 2005 Durango had issues. Toyota, Nissan, GM, FCA. Car based navigation units universally suck.
- How does everyone like having functions turned off when underway? Not even my passenger navigator can access important functions, like selecting a destination from the map, when underway.
- Then there are the update nightmares. $100-$300 for an updated map. Each year. Toyota's were the worst.
- Error messages and malfunctions: I've seen errors like "No detailed map is available for this area, turn by turn guidance is turned off". In a frigging nearby city laid out in the 1920s!
- How about routing insanity. I've been put on rutted out dirt roads in our 2003 Solara convertible. Updated 6 months before. The road has been dirt and rutted out for 80 years, yet the stupid Toyota Nav insists on using it.
- Lousy interfaces and impossible to read in bright light. In a car. Well duh.
Faced with this frustration, we use smart phones, Google and Waze. HOWEVER, neither work very well in areas without cell coverage and neither have routing options for RVs. NO its NOT fine to get routed on a road with an 11 foot bridge in a 12 ft high RV!
So that's why each of our cars has a car mount for our Garmin GPS unit, and my truck has a Rand McNally tablet based GPS. With either I can count on free recently updated maps and traffic information thru my cell phone. I can use Rand's website to plan long distance trips. I can do it on my tablet, PC, even my cell phone, and download the data anywhere to Rand's GPS. As for cost? How about 25% of the cost of a fancy car based Nav and all updates are free.
Again, why does anyone buy the stupid car based GPS?
