I am going to pickup the Kenwood KVT 512 in dash DVD head unit tomorrow.

Bestbuy has them on sale from $699 down to$380.

Seems like to good of a deal to pass up.

I don't want to walk in and have them try to sell me a $100 worth of adapters.

Is the Schosche VW-01B the only thing I need to hook this up?

I have the factory infinity w/nav(will be up for sale).

Will this new head unit use its internal amp and my factory amp? or will the factory amp become obsolete?

Thanks,
Mike
