I now verified that on TT6.030 you have to use "Other NMEA GPS/4800Bd/Com 4: and on TT6.032 you can stay with "Internal GPS"
In any case, TT6.032 with "Internal GPS" the fix is aqcuired a lot faster than on TT6.030
TT6.032 is supplied with the TyTNN II on the accompanying CDRom
(TT6.032 incidentally does not allow itself to be installed on any other device, the installer prevents that, but after installation on the TyTN II, the directory can be copied to for instance the x7500 to replace the old installation there, and it will work fine. My first impression is that also on the x7500 with TT6.032 the fix is faster, but I still need to run the "dinner table test"
