Just got my Z3 drive updated with the new maps from Garret. Again had awesome service, got the drive back in 2 business days from the time he received the drive. Garret is the MAN.
Also, he is very quick to respond to his emails. We traded emails numerous times, very helpful with all my questions!
Everyone should buy Garrets drives, even if you dont own a avic z series!!!
Thanks again Garret.
