Hi All. Anyone using the above satnav software on their HTC Desire? I purchased this at the weekend and took it on a couple of hours jaunt yesterday, only for the thing to lock-up my handset after approximately 1hr. I did try a couple of more times, but again it locked my handset up. The only way to get the handset working again was a power down and reboot. Which wasn't the safest of manuveurs whilst driving.
