So, I've been doing my research on this site, and I want to buy what appears to be (arguably) the best iPhone integration solution on the market, the Peripheral PXAMG. I understand that Peripheral and iSimple are either the same, or very similar. I called Best Buy to check availability of the PXAMG and PGHHD1 (or PGHHD2, I'm not sure which I'm supposed to get). Anyway, they did not carry that specifically, but tried to sell me the iSimple ISIM71. This is for a 2006 TL NAV.

Question 1: Is the Peripheral PXAMG and the iSimple ISIM71 the same product?

Question 2: Do I need the PGHHD1 or PGHHD2, and is it included in the ISIM71 package?

Thank you for your advise...
