For father's day I got a Magellan eXplorist 200 GPS, and I wanted to be able to use it on my bike. But in checking out Magellan's website they wanted $39.99 for a mounting bracket plus $6.00 S&H. Well, I knew I could make one for less then that (actually ~$20.00). Oh, and the dog in the back-pack carrier is Duncan, he likes to go for rides, so once this 'mini-project" was done, we hit the road.

Step 1: Materials required

The two items needed for this project are:
1. (1) Garmin Forerunner 101 bike mount (Part No. 0101-10482-00) cost ~$18.00
2. (1) Scotch Dual Lock Reclosable Fasteners (pkg of 4 - 1" x 3" cost ~$2.49

Also some rubbing alcohol and a clean cloth.

Step 2: Tools Required

A Coping Saw and a pair of scissors

Step 3: Cutting up the Garmin mount

The Garmin mount needed a little cutting, since it's a little bit wide for the eXplorist GPS. I cut the ends off both sides at approx. 1/4" from the lip of the reccessed area where the release lever is located (See pictures 1 & 2)

Step 4: Clean the parts

Per the instructions that are on the back of the Scotch fasteners, clean the bracket and the back of the GPS unit. I used Rubbing Alcohol because it doesn't leave any residue.

Step 5: Applying the fastener strips

Once the parts are dry (doesn't take long) you can cut one of the fastener strips into the pieces that will be needed. Cut two (2) 1" lengths of the fastener strip. Then cut those two pieces in half length-wise. So that you end up with four strips approx. 1" L x 3/8" W. Peel the backing off of two (2) of the strips and apply them to the modified Garmin bracket in that recessed area, against the edge of the lip.

Step 6: Aligning fastener strips

Next take the remaining two strips (leave the backing on for now) and press them into the two strips that are attached to the bracket. This is to make sure the strips are aligned when applied to the bottom of the GPS.

Step 7: Prep'ing GPS fasteners

Now you can peel the backing off of the strips from the previous step.

Step 8: Connect the bracket to the GPS

Line up the bracket with the bottom of the GPS unit and press it firmly against the GPS.

Step 9: Make sure the fastener strips are secure

Carefully separate the GPS from the bracket, so that you don't peel off the fastener strips. Then press against the strips, on the GPS, to secure them firmly into place. The rounded edges were still up just a bit during the previous step.

Once this is done, you should be able to safely separate the two. But the fasteners are just an inexpensive "adapter" to the bracket. It could also be used to mount other devices using the same method as I did on the GPS (such as a bike light, if you're short on handlebar real estate like I am).

Step 10: Putting it all together

Now just snap the bracket into the handlebar mount. It's mounted on my Specialized Tarmac road bike.

I did tether the unit to the bike, just in case.

Ok, saddle up and you're ready for some exploring or geocaching.

Come on Duncan, lets ride!

Step 11: Future project?

Hmmm, I wonder what these contact are for? This view of the circuit board is just under where the battery compartment is located.

This model doesn't claim to have PC connectivity, but when I opened it up, the Tx and Rx contacts suggest some possibilities (serial or USB connections).

Opened the link just because Duncan is so pretty. My parents have two dachshunds as well. I love them :)

I made a similar thing for a flashlight, for my mountain bike, and when I rode it the first time, the mount snapped - I was bummed. Point is, I could have saved my $30 LED flashlight if I had a tether line. For a road bike, the user should be fine, but who knows? If they hit a patch of bad road, it could pop the Velcro, and dash the GPS to the pavement. I am just trying to help. I think I would either attach the strap that comes with it, if there is one, or jam one inside the case with a knot in the end, and screw the case back on tight. Then wrap the strap around the handlebar, and pull the GPS through, then mount it. HTH.

Yeap, this has happened, but thanks to the tether, that GPS didn't hit the ground, I'll probably add a step to have some kind of strap. Thanks.

I can't believe it. I was just today looking on Amazon for a handlebar mount for my Garmin etrex gps. This article has inspired me to make my own instead out of a mount for an old bike lock I have. cool

Hackaday has an article with a link to a russian website (with english translations) that is exactly what you're looking for to answer the question about those mysterious contacts (RS-232)

Happy soldering!

if the adhesive on your velcro gets weak, you can just epoxy the velcro on. i do this with most projects, because i've found the adhesive on most of that stuff sucks. also, this allows you to work with stronger velcro as well. also, velcro attaches well to most anything with a nap.

Another thing while riding in the hot sun the adhesive may become soft and let go of the mount all together.

So far it hasn't, in fact I picked this particular type of fastener because it's used to keep the I-Pass units stuck to the inside of the windshield. They sit in the sun all day, day after day, and so far I've never found my I-Pass lying on the dash.

I use a few rubber bands in addition to the bike mount for the GPS on my bike. The mount itself doesn't have much of a positive lock to the GPS, so it bounces around and once the mount actually broke. I'd bet your velcro attachment could benefit from some rubber bands for that occasional super deep pothole.
fireballxl5 (author)  ewilhelm9 years ago
Yeap, I try to avoid the potholes, but even plank bridges and railroad tracks can tend to jar it loose. I had the same issue with the steady cam mount (no 'velcro involed there),

but I used a small bungie strap to help secure the DV camera.

there's an article on hackaday that shows how to use those connectors on the back:

I've been doing some research since getting the GPS and this site sells cables for alot of devices including Magellan GPS'.

http://pc-mobile.net/mex100.htm

And this site has instructions for making your own cables as well as oher info, downloads, etc:
