Thanks. Indeed, it works if I hold down the On button for a few seconds. The thermometer shows the exact same temperature as a de facto thermometer, though I guess that could change once the GPS unit is exposed to sunlight, body heat, wind, etc.

None of this works on my 60CSx. Anyone know whether this model also has a thermometer? Why isn't the thermometer accessible through the documented software? Such a feature is certainly mighty useful and could be advertised as a selling point.

Do rechargeable batteries work well in cold temperatures? In my experience, alkalines crap out pretty quickly in near-freezing cold. On the other hand, lithium batteries seem largely unaffected, and last around 50-100% longer.

No idea, but due to limits on the number of map sections, it might not be possible to transfer all of Topo USA. I'm using a 2 GB card, but could transfer only about 470 MB (80%) of just the Western US CD onto the 60CSx. A 512 MB card would have sufficed. Garmin tech support confirmed the problem and mentioned only that a solution might be considered in the future.

I was just working with my TOPO set, and I figure it will take 4 SD card to have the entire 48 continental US loaded on them. The US East has 2565 maps using only 658 MB, and the US West has 5187 using 1.509 GB If it was not for the 2025 limit, you could get it all on 2 cards Could you load the map segments in two or more map files on the card to get past the 2025 limit? Or does MapSource just overwrite the data each time? There may be a way, but it's not ideal. A map set seems to be placed in one file under the 'Garmin' subdirectory on the card, as can be seen via the Mass Storage feature of the 60CSx. Thus, after a transfer, you could rename the subdirectory (e.g., 'Garmin1', 'Garmin2', etc.). In this way, there could be multiple subdirectories for map sets, with the current active set named 'Garmin'. To switch to another map set, you'd have to rename its subdirectory to 'Garmin'. This requires a PC connection, which is why it's not ideal. Still, at least this is a way to use the full card capacity. I'm using a 2 GB card, which is the largest available today, but found that the 2025-tile restriction limited transfers of MapSource US Topo (west) to about 470 MB per map set. I also contacted Garmin to see if there are any workarounds, but they only reiterated the issue and agreed to consider a solution for the future.
