I changed my battery for my 2002 acura tl type s. Everytime i make an attempt to reactivate the radio by inputting the radio code, i keep getting errors. the guy at the dealer told me to unplug the black cable from the battery for few hours and then replug it back to the battery. He sounded pretty confident that it'd work. I've heard someone on the board saying something about 02 tl radios being defected and in order to reactivate, you'd have to unplug the antenna wire prior to putting in the codes. Any tips? I dont even know where the antenna wire is located. I guess i'll try the first option first. Suggestions?
