MY RER Radio has killed my car battery twice now. - 1/26/2008 7:42:49 AM    needforsleep   Posts: 75 Joined: 5/13/2007 Status: offline For those of you with an RER radio I found out from the dealer that the RER radio has a known hardware issue that can cause it to stay awake when you turn off your car.  This will then drain your battery.  The way to catch if your radio is in this mode is if you cannot change your volume.  If you turn off the car and come back to it 5 minutes later and the radio is still not allowing audio to be played then BEWARE your battery may be drained if the car is not driven soon.  I think the only way to get the radio out of this condition is to pull the fuse and force the radio into a hard reset but I have not tested this. Good luck for those of you with this issue because it's starting to be a real PITA for me. < Message edited by needforsleep -- 1/26/2008 7:47:29 AM > _____________________________ 2008.5 Dodge Avenger SXT - 2.4L Steel Grey - All Options Including REN MyGig + Rear Seat Video Post #: 1

Great.  I just picked up the car last night and there's already something wrong with it.  Geez... (in reply to needforsleep) Post #: 3

I would pull the fuse for the radio and kill the power to it.  Put the fuse in back in the morning. I wouldn't chance it. _____________________________ 2008.5 Dodge Avenger SXT - 2.4L Steel Grey - All Options Including REN MyGig + Rear Seat Video (in reply to Voodoo Avenger) Post #: 4

Especially the MYGIG. Pulling out the IOD fuse for 10 seconds and putting it back in may help the radio synchronize internally. Just like a home computer, modules can lock up or go crazy. and what do we do? restart it. with the radio being a module I would make sure the software for it is up to date.

Just curious...how long would it take for the battery to go dead? (in reply to needforsleep) Post #: 6

Tonight, when I put my ear up to the radio, I didn't hear anything at all.  I'm going to leave the fuse in over night and hope the battery is fine in the morning.
