If those are like the 2610 I have, look into the Garmin M/C kit. It comes with a locking bracket and hard wired power cord for about $40. You will still need a Ram or similar sys to attach the Garmin bracket to the bike though. If you use the Ram sys, once you get it set like you want it, replace the big wing nut with a self locking nut for additional theft deterence.PUREPLEASURE said:Whats the best mounting bracket, far a garmin 2820 or 2730 GPS,navigation system on a GL1800. 06 model!! :?
