Bro, is your MobileXT a legitimate copy? Otherwise it will not work with your Holux-1000.
I think so. So far no need to use any GPS bluetooth device to communicate with my HTC HD.
Currently, I'm using Garmin XT on my htc HD and Dell Axim X51V+ GPS bluetooth receiver Holux M-1000. It observed the my Garmin XT which installed in htc HD took about few seconds before showing 0 rpm even my car already stopped few minutes before. So, how could I improve the accuracy of the system. No problem observed on my Dell Axim.
Secondly, how could I the MFM updated into my htc HD?. Is it just simply removed the previous map and reinstall with the new one?. I just bought the htc HD and It was installed with their Garmin XT software. Since I noticed the map and POI are not the latest/up to date compared to what we're having here, the map was removed and then reinstalled with our map. Later problem observed where the GPS system cannot run smoothly.Then, went back to the shop, they reinstalled back the system and working well but sometimes unable to receive satellite signal when on highway and the speed (at GPS system) showing 0 rpm. So, how can it be solved?
