Ok, I finally got this mod finished. I've been wanting a GPS/laptop set for a while and I was patiently getting all the pieces together. I finally got everything hooked up. The GPS is a Garmin Vista, and I have Garmin Topo running on my Laptop. The laptop mount I got off ebay for about $60 shipped. Very basic, basically an acrylic table with pipe fittings which you can source from Home Depot....The laptop mount is actually quite sturdy, you can see on the link how I used a longer 8mm x 1.25 bolt much like another 80 series member did in his install (thanks bstain) but after a trial drive test, I wanted more sturdiness so I added another 2 bolts with larger washers from under the center console and fastened the base from the top...Much better, as my Saturday night run into Berdoo Canyon confirmed..
