Hi
I have recently bought and installed one of the DVD-993 DVD units and it actually worked first time. It did help reading this thread first to confirm the terminations etc.
It does stick out a bit from the fasia, installed in my daughters Peugeot 206.
Will need to take a chisel to the dashboard!!!
Bought it from eBay, as long as it continues to work I will be happy
At the moment it seems to do what it says it does, not bad !!!
I even connected an aerial and can receive UK TV channels in colour and with sound.

Thanks to David_M for the reply.
So Far So Good.
