Since there is not a separate sub-forum for Garmin Express, I'm posting here as these issues came up during last night's Lifetime Maps Update to 2013.40 that affected Basecamp and my zumo 665.
In an email reply to another rider, Garmin Management admitted to the following unannounced change:
"With Garmin Express, the map update will not be installed to the computer if the device has sufficient internal memory for the computer. This was a decision made by Garmin to simplify the map update process. I apologize for any inconvenience. You can view the mapping on the computer using Garmin's BaseCamp program. BaseCamp can pull the mapping from the GPS device when the device is connected to the computer."
This is disastrous on 2 fronts:
1) If your device has sufficient memory, you will be forced to mount it whenever planning in BC, resulting in painfully slow map loading (each and every time), route planning and modifications, and map re-drawing. This wastes all of the processing horsepower of your pc, and for cross-country trips, it is unworkable.
2) If your device has insufficient memory, you will be allowed to download the full mapset to your pc, but since Garmin Express does not recognize any installed SD card, and because Basecamp eliminated the map transfer feature, you will only be allowed to install a subset of maps to internal storage on your device - in my case, about 1/4 of NA on a 665, even though I have a 16GB SD card. So, for my trip from Colorado to Maine via Florida this summer, I would be required to carry my laptop and actually swap out mapsets on my device 4 times along the way.
It's impossible to discern what Garmin's navigating vision might be, especially considering these latest moves, but I'm quickly coming to the conclusion I'd be just as well off to tape a brick to my handlebars.
The motorcycling community absolutely must have the ability to load the full mapset to both Basecamp and the device+SD card, or Garmin has rendered their technology platform obsolete.
