A little update:
Just to show you how much I like my Parrot I just ordered another one for my Suburban, even though my Garmin nuvi navigation unit was fully capable.
Bonus with the Parrot is that the radio doesn't even have to be on to work and regardless of what input it's set to I'll get my calls.
I did get the GM adapter, I wouldn't do the install without it - 100% plug and play, no wires to cut/splice.
