Hi Jeff,
Yes, that link is very useful. I've read it before and shared it with some family members.
Sorry, but I don't use a cell phone to update GPSfix's. But I often update directly without using HOME. Don't see how this would help you with a blued tooth cell phone, but there are links for direct download. Depends on what version chipset you have on your TomTom on what file you need...
If it's
"lto.dat" you need, you can get it here:
http://home.tomtom.com/download/Ephemeris.cab?type=ephemeris&eeProvider=globalLocate&devicecode=AKWAQBAAQZ
If it's
"packedephemeris.ee" file you need, get it here:
http://home.tomtom.com/download/Ephemeris.cab?type=ephemeris&eeProvider=SiRFStarIII&devicecode=2
Just copy the one file to your ephem directory. The date will be messed up, but just ignore that.
