yeah, sorry about the backlash, I just hate internet tough guys and people that have to be condescending to make themselves feel better. I will try and play nice! 
I know motorola makes bt kits, I install them. he said 'older motorola hands free kit' which to me is like the ones you have to put your phone in a cradle, etc. I know that if you have a motorola, parrot, etc. BT kit, and THEN you buy the avic, it would be nice to interface the 'old' kit, but honestly, if you are spending the money for a navi unit that is BT compatible, take full advantage, and spend the extra few bucks.
just my .02 tho.
