I bought the kenwwod kvt-614 on craigslist and installed it. when I turned it on code screen appeared and I called kenwood . I was told I needed to send in with proof of purchase wich I cant do due to buying from craigslist. Is there anyway to find this code or reset it myself?Here are numbers found on stereo;y39-5980-11, NO.90200698,& 490 1062205
