Hey, Its my first post ever and i was thinking of installing a nav screen to my 06 coupe, It originally came w/o nav unit just the bose 6CD changer unit, I've looked online if anyone added oem nav to non-NAV ones bcs my idea is to get one outta ebay or smth then take out the screen and everything and do my own pcb and screen or maybe putting raspberry pi to turn it simillar to the r34 MFD
