Tom Posted September 11, 2013 Report Share Posted September 11, 2013 I have a red G4 Xtreme with harness built for my car, which I have been slow to install, so is still sitting new in a box.Â Should I still install the G4 box, or upgrade to the G4+?Â Is the G4+ pin compatible with the G4 (so that I can use the same harness)?Â Will Link continue to support the original G4? Is there a chart somewhere comparing the new features of the G4+ over the original G4? Quote Link to comment Share on other sites More sharing options...
