I have not pulled my stereo yet but you might want to replace you speaker wire in older cars that could be a problem also. You should pull your head unit and just look at it then report back to the forum. iF it is the same.
The stock harness should be the same as the radio your looking into getting, should have no problem being installed. The only thing that your Avalon might not have is the second harness for the stock amp. I'm not sure but thats what I think the second plug is for.
Any stereo/cd player that begins with AD- will fit. for example AD-6801..I took had that problem with mine, as I only had the tape player...so I upgraded it to a CD, such as AD-6801. This wshud answer your question...any others feel free to PM me
