Ok guys, been a while since I posted something here but I may have stumbled upon something . Can anyone confirm this part number P68283555AB for the radio module. Im in disbelief if this is an re2 or rb5 (Navi) unit. I did some Google searches of the part number myself and the results I got we're it being an re2. But I need someone else to confirm this before I shed some light, depending on the info found on part number.
