Pretty happy quality-wise. Haven't used it much since the Crossfire is in the garage for the winter . My only complaints so far are the 2gig max SD size, and that you can't resume playback from where you left off if you turn the car off/on or switch sources. But the audio quality is great.

The paint was a can of Tamiya spray paint. Got it at a local hobby store for ~$6.00.

The bluetooth connectivity is neat, and seemed to work well enough without the external microphone. I had my phone in the storage bin and made a test call - the audio came across clearly on the speakers and the person on the other end said they could hear me, but there was some occasional buzzing that came and went.

Overall, I am pleased with the purchase!
