Navigation Screen Blank JGC
My navigation screen went blank yesterday. I started the vehicle no screen, could not change between AM/FM/CD/SAT. Volume and preset buttons work, as well as UConnect hands-free phone. Tried disconnecting the positive terminal of battery for 15 minutes to reboot the system, a no go. Replaced the 30 Amp fuse, nothing. Now after disconnecting the battery my main red airbag light is also on. The dealer wants $129.99 just for a diagnostic that they will not waive if work needs to be done. Do not want to dump money into having to replace the Nav unit. Any suggestions?
