On the theory that honesty is the best policy ...
I have a 1490 Nuvi that WAS working well. My wife left it all day in the hot Florida sun. Now, I no longer have a map. Garmin sent me another update but I can't download it.
My error message is:
"Since our map data gets larger and more detailed each year, the full coverage map requires more memory than what is available on your device.
Please select one of the regions below to install to your device."
The problem is, the screen shows a drop-down menu but it is blank (i.e. nothing to select).
Any ideas ???
