I'm still running an ancient Garmin 2610, and some how I lost my cable that allows me to plug into a computer to "update" stuff... now it's useless, and won't aquire the sat's..
I think I'm going another route now, and picking up the Garmin "remote" plug in Sat antenna, and software, and mount it on the bike, and use an older un used now "tablet", for my screen, inside the clear cover on my tank bag.
That gives me a screen like 4x larger than my GPS... old eyes like that idea...
just have to find a work around to get power to the tablet.... it only has one micro USB, as a data or charging port.. and even tho the Sat antenna has a usb for power, it has a data wire to computer output usb also... hmmmm gotta call Garmin...
