as the mrs is the boss, and she wanted a factory look, she bought a gamma tape player from eBay for £29 with a code, I put it in and hey presto it works and so does the cd player that was in the car!
it's maybe a little more sensitive to bumps than a new one but still works fine!
very pleased with it overall, the kenwood unit the previous owner put in was a real dodgy job - no surround, cage all mashed up and visibly deformed, cd player didn't work, was wired to permanent live, etc etc etc
only issue now is I THINK one of the tweeters is blown or damaged in some way, can't seem to get good treble
