There's a discussion about this map in the "GO" forum, but I have a ONE, so I'll post my experience here.
Home told me that a new map was available, United_States version 830.2323. Yay, the first one in my subscription. But will it work?
* I backed up my unit. Full "Explorer" backup. I've heard enough stories of borked updates to know that's the first step.
* I let Home do everything *but* the map download. I wanted to get my last round of MapShare corrections transmitted (I had several from drives through the country this weekend).
* Then I let Home upgrade the map. Download, install, no problems.
* Just for kicks, I checked for updates again. There are already some MapShare corrections (but I don't know how many, because Home still won't display it).
* Used the "eject" button in Home to disconnect the unit.
And here's the result:
Problem with map
You cannot use this map
on this device:
United_States
[Continue]
Pressing "Continue" gives me a map selection screen. With only one option: "United States", which generates the red-screen error above.
Power off, power on and run Home again. Sure enough, even in the Home emulator, I get the red screen error.
Guess I'll send an email to TT... I'd call, but I don't have time.
