I am searching for the pinout for a Garmin 2720. My wife borrowed it for a trip to North Carolina a few weeks ago, and left the cable in the rental car. I was looking for it yesterday, and she mentioned that she left it. Could have mentioned it sooner, I think. I am about to leave on a motorcycle trip tomorrow morning. DOH! I know I can make a temporary cable from some bent flat pins and a credit card, but I don't know the pinout. Can someone find a diagram, or tell me which pins to use? I have been searching, but it has been fruitless. For example, it's possible to get pplugs for some garmin models, and often you get a nice pinout diagram as well, like here. But the 2720 uses a "rounded triangle" shape thing. Thingy. Whatsit. Help?
