I have a 03.5 G35 Sedan and had a parasitic drain issue. It was draining my battery overnight! My CD had the dreaded CD FO ERR mesage. Took it to the Stealership, and they couldn't find the source of the drain! I then took it to a auto electrical shop. No help there either. So I took it to Radio Medics in Rancho Cordova. They replaced some broken gears, bad motor, in the cd player and a fried chip in the power supply. CD player is now working better than ever and my drain problem is fixed. I guess the power supply was somehow draining my battery. Anyways, if you're in the Sacramento area, go see Fernando Cruz at Radio Medics on Sunrise Blvd. He 's seen alot of these broken BLOSEs and he's the MAN!
