so i changed my battery the other day and all my shit reset, but for some reason the nav won't let me put in my 'go home' address, cant get to my address book, or calender... anyone know why that would be all other settings were still good in terms of seat steering wheel, just seem the nav reset and is locking me out of those 3 areas anyone have any idea whats going on

 

nevermind it popped back up again i guess it had a make the owner go crazy for a day RL syndrome.....

 

For future reference, this happens whenver the battery goes dead. Park it outside and let it run with direct line of sight for 15 minutes.
It will eventually recover.
