I have just switched from Nokia E72 to my first Android phone - Desire. I am curious; I always used the ovimaps for navigation with my E72, always with my bluetooth headset. I tried to do the same with Google Navigation on the HTC Desire but I just could not get the sound on my bluetooth headset. It still came from the device even though they were paired. Is it possible to get satnav voice off the paired headset like Nokia device?
