There is also a guy who will take your stock AM radio and convert the guts to new specs that are identical to the radio that sells for $599. He uses your stock AM radio converts it to AM/FM/iPod input, 80 watts etc. Your radio still looks like only an AM radio, but when you turn it on and off and back on it goes to FM. I know someone who has this and it looks, works and sounds EXCELLENT. This guy does the conversion for $399 plus $20 shipping. I'll get his info and post it...
Here is his E-mail: bandit235@comcast.net if I remember correctly his name is Mike. Also, the radio you send him does not have to be a working unit as he guts them anyway.
