I'm writing to see if anyone else has had this issue, when I select Nav in the top right corner of my 430n it just pulls up the Garmin screen and stays there for hours. My car is a 2014 SRT with 4000 miles and the nav has never worked. I have taken it to the dealership 3 times and they finally told me dodge has a patch coming in the second quarter of 2014 but that has already came and went and now they're saying October. The guy at the dealership says that this is a known problem but yet I cannot find anything from another person with this problem anywhere online. Frankly this pisses me off any advice or information would be much appreciated.
