My 660 had a nervous breakdown

Coming north to Door County, highway 42 has a new section. Jack kept recalculating trying to get back where he thought the road was. After a few minutes he froze up. The unit simply stopped doing anything. I shut it off and turned it back on. By then I was on the mapped section of road and it worked fine. I've been on unmapped roads before and this didn't happen. Is this a normal behavior?
One freezeup...
I've had one freezeup on my 660, a few months ago, and like yours, a reset cured it -- no twitches or weirdness since.

660 With A Nervous Breakdown
geochapman,
I have a 650 and have been on a newer section of an interstate and it would try to have me get off at the next exit and turn around. This went on for five exits until it must have finally reached a section of the road that was in its "map" memory and continued on without further problems.
I have never heard about the problem that you encountered.
Have you spoken to the people at Garmin?
If that fails, have your 660 take two aspirin and rest overnight.

In the Middle of Nowhere
I have encountered problems with my 660 when driving on unmapped roads, but never had the unit freeze up. In Edmonton there is a new freeway that goes on for several miles, but is only a couple of hundred yards of existing roads on either side. My nuvi just shows me travelling in the middle of nowhere (a grey area on the map). In other instances, the unit continually repeats "Recalculating. In 100 meters make a U-turn." I assume that if you're close enough to a mapped road, it will allow you to continue.
Map freeze
I have had my Nuvi 650 freeze up. It seems to happen when I don't follow its directions and it tries to recalculate and then freezes. A reset usually fixes this.
