I found that info prior to arriving to this forum. Some guy in Russia sells the PCB to replace the one Garmin installed in their data cards, using the same casing. at the cost of @ $150(?), it's NOT worth the price for this GPS when I have 2 newer Nuvi's that works flawlessly AND fully updated AND paid for.

I can only use the mapinstall if I have the maps to install, partial or otherwise.

My issues are trying to load\send the .img images to this unit, which I CAN NOT DO, as with the Nuvi's. Nuvi's are simple, just copy and paste the downloaded .img into the Garmin folder and it's up to date.

At least now, I got the 2012 map installed, instead of the original 2008 that came with this unit. Although it's still 3 years out dated map, better than 7 years outdated map.

I'll check out the links provided and see if any of them will direct me on "how to" install .img files to this unit so that I can be fully up to date with 2015 .img map file I found.
