ive got the garmin bike mount for my quest, the power cables on it are really tiny, like 0.5mm squared or something. the inline fuse that was built into the loom was a bit nasty too, a 240v glass fuse! didnt know whether it was good or not so i kept it on, soldered on a BMW size plug and heatshrinked the whole thing. this goes in the accessory socket that has a 1A fuse.
