Punch a hole in the back of the GPS? A mount made for the model of GPS will have a space for the power cord.koji52 wrote:My suggestion if you don't want to spend alot of money on the gps itself is to buy a RAM mount. They are seemingly waterproof and come in various sizes so you can buy a standard automobile gps and throw it in the RAM mount when you're on the bike. Mine works well and water hasn't been a problem. However, using a power cable means punching a hole in the back and that's where the waterproofing becomes questionable.
Two very good companies that sell GPS/gadget mounts: cycoactive.com and cyclegadgets.com
