Hi, the 99 4runner base model I bought came with a pioneer what I believe you young people call an audio system. It has mp blah, blah, blue teeth something or other, and flashing disco lights that turn all different colors, and hole to put something into it that I don't even know. I'm a senior citizen for Christ's sake! I listen to talk radio and a couple of classic rock stations. Maybe a few CD's now and then. I downloaded the instruction manual for it, but it might as well be written in Chinese. I'm not gonna lower myself to get a 16 year old kid to program this thing for me. I get enough crap from someone in India to help me with my computer. So my question is...If I can find a stock radio, what should I be looking for. This much I know, it doesn't have a diversity antenna like my 2000. I don't think it has an amplifier, but I'm not sure. I don't know if they fecked with the original speakers. I know the push in plastic rivets on the door panel were missing, so at one time or another, somebody got into both panels. What they did in there, who knows. What should I be looking for on Ebay and will it work? Some of you boy scouts out there, please think of this as helping an old feeble man across the street. Thanks.
