I updated the map 207.20, JVC, and 3d image file from this site the map is on a 4gb SDHC card and the other files were installed into the unit. I now get a "No Data Available" message when trying to enter into any menu items. I tried a reset and any firmware and software updates still the same also it does show the new map on the card and the box is checked. I did have a backup of the original files when I purchased this unit moons ago but have lost them.
Any help in trying to resolve this issue most appreciated and thanks in advance otherwise time to discard it and purchase another new unit.
