I am posting this because I was unable to locate any info when I was doing research for GPS units for the Q. Purchased the Garmin mobile 10 to replace a Hyundai Pontus, it was to be used with a Sprint Motorola Q running Windows Mobile 5.0. The OS on the Q is Q2-BP_C_06.26.00R, the phones have a 2 gig mini sd card installed. It was a slow start getting things running, about 3 days, but once off the ground I was very happy with the Mobile 10. The software that came with the unit was not able to connect the phone to the Mobile 10 (a blue tooth problem). This took a phone call to Garmin to solve, but after downloading the latest software from the Garmin web site that problem was solved ( update 40060W.exe). The second problem was a setting in the phone that I had changed to get active sync to see the phone. Because of the firewall on my machine, I had to uncheck the “Enable advance network functionality”, this option MUST be on for the Mobile 10 to work, or it will hang searching for sats. The third problem was caused by having a older map set on my machine. It took a second phone call to Garmin to figure out that the software defaulted to the version 7 maps (the last used) and a simple click on a drop down list to change to version 8 maps had me up and running.
Pros: The software uses the phones internet connection to check traffic and displays the problems in colors on the map. I can receive and make calls while the software is running. I have installed the software on three phones so any one using the car at that time can use it. So far I have not had a single crash. Map4pda will find and use the Mobile 10
Cons: this is more a problem with the phone than the GPS, the Motorola Q can not use the messaging feature of the Garmin software to send your location to others.
The Mobil 10 does not work with Google Maps, smart2go, or live update without using a hack or gspcom.exe, and using either will interfere with the Garmin Mobile XT software
