I don't have any clue about Alpha, but If nobody answers you, contact Jimmy07, He's an electrical expert.OK, so I looked through the AlphaOBD while not connected, and see a rear park sense option. But when I connect it through an SGW gateway, and Bluetooth Veepak, it's not there. Help!
When driving my Durango, I hit the four ways dozens of times, because the idiot engineers designed a switch that sticks down from the dash, right above the console, where the phone slot is.Ugh, simple fix. My phone/holder was blocking that I accidentally bumped the rear parking sense toggle. Light was on. Now all is good!
