Junk barely made it out of warranty.

I installed this for a customer, it is very difficult to find a very plain basic radio for older clientele. My customer is older (80's) he needed something simple to operate. I decided this Boss 637 UA would fit the build. I installed the radio using the harness adapter(s) and dash kit. A month or two later he was complaining of no sound I instructed him to bring it back thinking he stuck it on mute or something. I tried cds aux fm everything no sound the other features still worked it was just junk. Sonic Electronix took care of the warranty . I have no complaints with Sonic or they're customer service. I would not recommend this radio however.
