Hi all. Just installed VTL300 on my D2. It works fine when I go into rear camera mode but it's half screen and won't turn on automatically when I put into reverse.
I orginally had the unit installed professionally. The reverse wire from D2 seems to be going into the engine bay via firewall.
Do I need to tap into rear backup light in order for this to work? I am currently getting 12V and ground from the headunit.
Thank you in advance!
