nedd help finding visteon mp3 internal amp part
 

I'v had this visteon machmp3 in my ranger for about a year and a half and it desided it wasn't going to work anymore, it turns on but no sound. i spent 410$ on it thru the technicar in orlando and i can't seem to get any info on them eccept this site. I was quoted 275$ to repair it by a dealer who repairs visteons. I'm better off getting a new radio. Can i get the part and if so how much, do i have to go thru them to repair it , can i do it, or have someone with a soldering gun do it?
