I just installed a Kenwood KVT-512 7" flip-up DVD with iPod (in the glove compartment) interface tonight.

Install was straight forward using the Metra 70-7712 adapter. I had bought a lesser adapter off eBay that was supposed to work on a VCROSS, but a few contact pins were off. I was worried the whole time I was wiring, even after getting the Metra harness, as the stock vehicle harness does not have the universal wire colors for speakers +, -, etc., but this harness nicely fit the bill.

I am impressed with how a little extra amperage makes the stock speakers sound so much better.

No cutting of dash hole; used the mounts from the factory head unit; can't use the Kenwood beauty ring as our radio sit behind the dash hole, but I will cut a rubber membrane to fit over the outside of the radio before I put the dash on next time to mask the 2-3mm void all around.

The XM interface is due in next week, so it will all come out again for that, and I'll save my pennies for the navigation unit in a few months. After that, 6 1/2" rear speakers as they sound the most anemic in my VX.
