I wanted to try my GPS on my cruiser. The mounts I found on the 'Net for a TomTom unit didn't get the best reviews. I built a mount using two peices of 1/8" aluminum. I sandwiched the factory suction cup mount between them by cutting a hole in the center of the top peice. I bolted it in the corners. I'm going to get some bolts that don't protrude so far. The brackets are for hanging conduit. I padded them with felt.
