I need some advice please, from anyone that knows... I'm having the AVIC-75DV-2 nav package installed in my car in a few weeks. On an ice type web site I've seen it stated that this package requires the inclusion of an AV master (AVM-P9000R), but the guy that's installing mine has suggested that this is not necessary, but instead, the head unit that contains the screen (AVX-7300) has the required amplification built in. The Pioneer web site mentions nothing about fact and figures for amplification like it would with a CD tuner say, and I'm wondering what the deal is!

If anyone can tell me what the score is with this, I'd be very greatfull.
