I recently had a small issue with a Bluetooth GPS device and Mappoint 2010. It wasn’t able to communicate with it at all but if I used any other software it had no issue what so ever. So i researched a bit and found out that Mappoint has a few issues with Bluetooth GPS devices. Anyway long story short I found this great software called GPSgate. It is originally made for using the Bluetooth devices in more then one software at the same time. However it works great with Mappoint.
Once installed you can simply set the software to use the Bluetooth GPS and publish it one or more COM ports.
If you are not going to do anything crazy and really only want the software for Mappoint or Streets and Trips you can use the Express version which won’t cost you too much. So here is the link to the client:
And here is the link to the purchase page for the Express version:
I hope it works for you as it has for me
