been doing some searching but found nothing definitive so here goes. several weeks ago the radio(radio/cassette) starting acting up, couldn't change channels, no volume control and so on. then a dead battery after sitting for a few days. removed radio, new battery alls good, reinstall radio(wouldn't turn on or ask for code) bam, dead battery the next day. radio out still holding recharge on battery. radio failure common? also read that a weak key fob battery can cause similar problems by not being strong enough to turn off the immobilizer? changed that. any advice?
