Transferring maps using MapSource or MapInstall will always produce maps named gmapsupp.img, so you have to rename them (Explorer) before you send the next to the device / memory card. If you have ready map images downloaded, you just can put them on your device / memory card using Windows Explorer.
I use a 8GB memory card with about 10 map files on it with my Oregon 400t. On the internal memory I have loaded some OSM maps beside the original maps coming with the Oregon 400t. So all together ther are about 20 maps in my Oregon, all working fine. The only restriction is, not to have more than 4000 map tiles on the system in total (number of tiles you can find out using gmaptool). So just enjoy live with your Oregon!
Btw it does not matter which kind your maps are of (G2 / Vision / NT etc.)
Is it possible to name maps/charts a descriptive name ending with "img" now too with the latest firmware? ( v4.0 firmware)
