Has anyone found that the XT will not route properly with OSM Street Maps?
When I activate these maps I lose Distance to Next Turn and Speed Limits. If the route includes a Waypoint I can't get past that! The unit keeps trying to route back to that point, even trying to skip the waypoint leads to odd random routing.

Probably the map, some OSM maps cause issues.

Hardly any I use for example include speed limits, if you use OSM maps you can't expect them to work exactly like Garmin maps

Hmm, first question for problems with 3rt party maps - did you disable the original City Navigator street maps under 'MyMaps' on the Zumo XT?
Two routeable maps activated at the same time makes for sure troubles...

Very true. I wondered once why my Garmin map wasn't working normally then found a recent software update had enabled an OSM map I also had loaded

Thanks for the replies. Yes I'd tried disabling the CN standard maps - no difference. Seems to be as Sussamb suggested - third party maps just throw wobbles! From now on I'll stick to the standard maps when routing through anywhere new and use topo maps when just bimbling about! Every day's a schoolday!
