#1 - Parasetic intermittent current drain that has killed 4 Delco and one Oddessey battery in the past 2 1/2 years. I think I hav isolated it to the Radio/GPS unit. Dealer had once for two weeks with the super GM Super Tech 2 tester which checks for current draw and they could nont find anything. Took out radio fuse and it seemed to work. So now I just turn off radio when I shut down and it seems ok. Any one had this experience??
#2 - Now GPS unit resets itself every time I shut down and when starting the H2, the GPS reads we are in NY and the local time is set to NY time with all memory of previous history gone. Any suggestions??? Thanks!!!

 

It sounds like the GPS/Radio had a surge or something & got fried. I've had electronics drain batteries faster after that happens.

You might need to replace it.
