I tried to add a CD player on my 98 Camry V6. After several hours' try, the mechanic said he couldn't put it in. Then he put my original radio back.
Several day's later, my car was dead. I got it checked in another shop and it turned out the radio drain the battery. I don't want to go back to that guy because I don't trust him, so I decide to work it out myself.
Now the radio works no matter if I put my key in ignition, not bad but it fry my battery just in several days. I take out the radio and find there are 2 wires twisted together! I believe they are constant and acc. That's the reason why my radio works without the key in ignition. But after I take them apart, my radio doesn't work at all, no matter if I start my car!
I checked both radio fuses (one under hood, one beside driver's seat) with multi-meter and they are OK.
I am totally confused now. Please help if you have any clue. Thanks a lot!
