Factory H3 NAV

[BB]

f5fstop, thank you for your reply. Could you tell me where the vehicle communications interface module is located ? The shark fin in the picture is not the one for H3, but similar one. A shorter caox with a black connector is for GPS. I believe that the one for H3 should be the same.

Hummertech, I know that an aftermarket Nav system comes with its own GPS antenna. But, I want to use the shark fin because it's already installed on the roof where the reception level is highly good.
