Backup Camera Interface for H3?

I've searched around for a true plug and play backup camera interface that will connect up with my GM GPS/Radio touch screen. There are a lot of backup systems out there, but not too many that will truely interface with the 2006 H3. At the moment I am using one of those $30 rear lenses and it works ok. It would be better to have a good backup camera.
Does anyone know of a good source to buy from? Any experiences with a backup cam?

I only have experience with the Pioneer systems. They are very nice. something like a 160 degree field of view! But you would have to switch to the pioneer screen unit. You might be able to get one for a fair trade if you sold your GM nav system on ebay..those seem to be bringing quite a bit of cash.

Thanks... I'm going to try to stay OEM. The trouble is finding a interface that will work with it.
The only units so far that they came back and said "Yes it will work with my H3" is the VCI-X from PAC and the AVElectronic unit. Has anyone used any of these before?

PAC interfaces have always worked great for me!!!

Thanks HB.
Have you used the Video interface and was it easy to install?

I didn't have to use that as I have the Eclipse Head Unit. But I've used PAC for my Steering Wheel Controls, On-Star and Door Chimes.
