Smaay Posted October 24, 2007 Report Share Posted October 24, 2007 i have a AVIC90DVD on a 6400 screen. about 3 weeks ago the navigation stopped working. i could see real time but no longer add new destinations, and if i picked POI the screen would go blank then turn white. so i was hoping the DVD was bad. well i bought a newer DVD on Ebay. not a copy but original. Loaded it and it appeared to update the system. after 2 status bars finished, the system reset. now its saying i have in invalid dish, please replace with correct disk. and my old disk does the same thing. worse than that, the radio and CD and DVD features are all locked out too.. HELP!!!! Quote Link to post Share on other sites

Smaay Posted October 24, 2007 Author Report Share Posted October 24, 2007 40MT i believe, i think i figured it out. the system is looking for a touchscreen and my 6400 is not. im going to try to downgrade the system. Quote Link to post Share on other sites
whtcrxghst Posted October 24, 2007 Report Share Posted October 24, 2007 Ya, if you can find a 40R it should work Quote Link to post Share on other sites
Smaay Posted October 25, 2007 Author Report Share Posted October 25, 2007 well the downgrade steps worked, im back to square 1. so why can i not enter new destination? its grayed out. all i can do is map search Quote Link to post Share on other sites
Smaay Posted October 26, 2007 Author Report Share Posted October 26, 2007 HELP folks...is the DVD bad or my system? Quote Link to post Share on other sites
mazda_3 Posted October 29, 2007 Report Share Posted October 29, 2007 sounds like your oparking brake cable wire (which you should have grounded) has failed if you say the functions are greyed out make sure your ground wire is ok Quote Link to post Share on other sites
Smaay Posted October 29, 2007 Author Report Share Posted October 29, 2007 well the wire was grounded, but its possible that it came ungrounded. but would that cause the screen to go white when i do a POI search? Quote Link to post Share on other sites

Smaay Posted October 30, 2007 Author Report Share Posted October 30, 2007 so could there be something mechanically wrong with my system? Quote Link to post Share on other sites
