fery Posted September 3, 2013 Share Posted September 3, 2013 Hi All, My navigation stopped working after plugin a charger to the dead battery. I got "A program cannot be read. Please consult to a dealer." I found in web sites, that the firmware on my navigation unit is gone. Replaced my cd with couple of different cd's but no luck. Is any body know how or where I can find Firmware CD? RX400h Thanks Quote Link to comment Share on other sites More sharing options...
maseace Posted September 3, 2013 Share Posted September 3, 2013 Did you try reloading the original nav DVD? Maybe you fried something by connecting the charger directly to the battery while installed in the car? Quote Link to comment Share on other sites More sharing options...

Most dealers are pretty nice folks and might be able to at least give you a starting point. Paul Quote Link to comment Share on other sites More sharing options...

I checked other people with same problem get result when they load a Firmware CD. Quote Link to comment Share on other sites More sharing options...
