Have to agree with damagedspline. Having had a N900 and an Android side by side running Waze - the Android version performs perfectly and N900 had no routing. Seems likely that the continual server upgrades by waze.com sometimes leaves the older Waze version's protocols inoperative.

On west coast of US I have currently have routing and network operational. This is after one year of no routing. Routing suddenly started working 2 weeks ago.

The revised [Realtime] configuration causes Waze to lock up completely on my N900 in my location.
