Bought a Sony Xplod Headunit off him:
Item came quick but did not work when it got here. Was afraid it was burnt up so I smelt it and it didn't have a burnt odor so I figure it could be something simple. Sure enough after looking it over good there was a pin just under the faceplate that came loose. I just pulled on it out and it popped back into place and after that it worked great. Guessing it was something that told the unit the faceplate was attached/de-attached.
Anyway I think this happened during shipment even though it was well packaged and don't blame him nor do I think he tried and sell me a busted radio. Luckily I wasn't clueless and figured out the problem. I could have been a real problem if it was sold to the wrong person
Overall I got a good deal on it and would deal with him again anytime.
