so yesterday my battery worked fine...

was not super cold last night .. but was cold...
this am .. battery dead..
jumped it .. got truck running ... and screen is blacked out .. no nav.. no radio .. no nothing ...
drove it around for about an hour .. hoping to charge the battery .. and ....

you guessed it .. NOTHING
still black screen .. and indicator is still red on battery ..

anyone?

 

anyone?

 

I got nothin'. They are complex machines, but let's start with the basics.

Is the fuse for the radio etal popped?

 

Nope all fuses good

 

not sure what i did .. sat in car for 20 min .. pulled 4 fuses from kick panel and double checked them .. put them back in and all of a sudden everything works..
even the intermitten remote start is now working

 

For a lack of other ideas, pull the negative battery terminal for about an hour and reconnect. Its worked with the nav position errors.

Probably won't help but can't hurt to try.

OK, now I re-read your last post, never mind. But pulling the fuse did the same thing. Seems like all else fails reboot.

 

Yea did that when my nav was off and fixed it
20000 miles now no issues
