Got my Holux working too
Even though I was very nervous about the Holux, it has proved for me working very well, but it did take a bit to get things working.
At first, I removed all bluetooth devices, then installed Towas' Patch and then added the BT Devices (Holux + HBH-65). The HBH-65 worked well all the time, but once I loaded the Holux supplied software GPSviewer, it kept crashing and froze or it automatically kept rebooting. Tried all different ports but no success.
Finally, I had to Hard-Reset the XDA2 and then first install Towas's BT Patch before pairing any devices or installing any applications. Then I tried some third party software and finally Mapopolis and saw it working perfectly (COM 5, 9600). For some reason, GPSviewer is not compatible with either the XDA2 or Towas's Patch at any setting.
The Positioning is very good and usually have 8 sats locked out of 10 visible. I saw the device to be very accurate, perhaps to about 1-2 metres on Mapopolis. I even get around 3-4 Sats locked when I am indoors (thats either on the top floor or near a window. First time to fix is always around 30secs and hotstart seems immediate to me. The only matter which has got to me was that while driving, the positioning seemed to be lagging behind and Mapopolis came up with streets which just passed. I am also quite pissed off with the male voice of mapopolis as it sounds awful. I have now ordered TomTom V.2 and will keep u guys posted how that goes.
PS: The BT Handset works well at the same time as the GPS, but still missing the Handsfree BT Profile.
Anyone any update about O2 (UK) ROM Update?
