Have a used GMR 18 (not HD). May have the power cable. Data cable didn't survive the removal. Cables should be easily attainable from Garmin. Worked fine when I removed it. Replacing it with a bigger open array. It's yours for the price of shipping if you want it.
I'm tired of fast moves, I've got a slow groove, on my mind.....
I want to spend some time, Not come and go in a heated rush.....
