I had that problem too for a while but it seemed to go away when I hooked up my system, you might try unplugging it or resetting your car but unplugging the battery for a good 30 minutes...and let everyhting reset, mine was acting funny too, took it to the dealer they had no clue, so when I put in my system it all went away, so my guess would be to try and reset your car... just a thought or recommendation however you want to take it
