FliteCharts
The first upload was no problem off of flygarmin.com. The second upload I had to manually upload which is an option on the right side of the screen if all else fails. I have the US TOPO's and they work great. I also bought the plug and play street maps on the SD card. The unit will not let me unlock the maps. I called Garmin the tech said I should have no problem since the SD maps were not lock. I received the second card and had the same problem. Anyone else out there with the street maps?
You can load the TOPO's through the unit itself or through your laptop via SD card. FliteCharts are taking me around 30 minutes to upload.
