I just got this 05 640...been able to put a grand sum total of 150 miles on it so far. These guys really liked it. It must be about 4 years ago that a friend gave me my first GPS...a Garmin V...I have a 276C now. I'll admit it...it's hard to leave home on the bike without one now. So this was obviously the first place to start with setting up my new ride. I wanted the GPS to tuck into the front fairing nice and close...there was just enough room. First thing to do was secure a base to the bike. The rearward of the two bolts connects to a small bracket I made which attaches to the bikes frame. Both this bracket and the base in the pic above are cut out of 1/8" aluminum plate Next thing to do was attach the Touratech cradle to my base. I also added a diagonal brace to the setup. The stock flip up GPS attenna wasn't gonna work with how tight I wanted to get this thing into the fairing pocket. I went with the remote auto antenna on a little shelf I added behind the GPS. The Touratech cradle I use is actually the one Touratech sells for the 176. I like it's flat design better than the triangular one they sell for the 276. Fit's in there nice and custom like. I also added another bracket to the Touratech cradle. You can see it on the left side of the GPS in the pic above. The latching bar on the Touratech cradle doesn't do much for holding in that left side of the GPS. I've had my GPS come loose and almost fall out a couple of times...not good. On a recent trip out to see Gary Emig I saw this mod on his bike...he's had the same thing happen to his 276C. I know a good idea when I see it...all credit goes to Gary for this little bracket mod. Here's the bracket I made. The knob came from Lowes, and I drilled and tapped a hole into the side of the Touratech cradle. I epoxied an additional piece of 3/16" thick aluminum to the inside of the cradle, inorder to get some more threads in there. You can see the additional piece in this pic. Like I said, I've only ridden 150 miles, but the GPS seems rock solid so far...and it's mounting location puts it in my field of view better than the install I have on my GS. I'm happy with this install. Next thing to do is add an additional fuse block to power up some heated grips and my heated vest... ...plus hard wire the GPS.
