--- Comment #14 from Mike mike@bleeding-head.com 2008-04-11 21:14:32 --- Yes. I just tested it with Wine 0.9.59, Ubuntu Gutsy, Mapsource 6.13.4 and a serial connection to a Garmin eMap GPS with firmware version 2.75. Downloading from the GPS works, but uploading doesn't work at all.
If there's anything I can do in the way of testing, etc. to help resolve this, please let me know. If this one miserable bug were fixed, I wouldn't have to carry around a copy of Windows on my laptop. Thanks.
