1st lemme start by saying the radio is AMAZING, but... It is REQUIRED to have the RR data link module just to power it up. There should be a big warning on the site when trying to order this that it is required. To my disappointment received the head unit and then had to turn around and order the module(few days later received that). So please let people know they need all the parts to operate!!!
