I got to use the 660 in the Jeep this weekend in and around Vancouver....I'm disappointed. My 6 year old TomTom with 3year old maps works better. The 660, between YVR and the Horseshoe Bay Ferry terminal recalculated more than 20 times (I lost count at 17...and it recalc'd a few more times). That's not so good, as it decided that I should have turned at the intersection I just went through.....a few times!....so, recalc again......
Turnoffs with street names that have had the same name for 100 years are wrong. Granville Street...that's a new street,right?
The only speed limit that it has displayed in Canada has been on part of HWY 1. TomTom does not do them all, but, probably almost half.
Lane assist does not acknowledge a lane as a turning lane if you have a choice of going straight or turning left( or turning right as well in some instances) in that lane......it kept me in the far left lane...waiting and waiting...until I got around the curve leading to the turn and could see the lane signs.
On Hornby Island, it had me drive right by the turnoff to the ferry that was a couple hundred yards away, around a curve so it was not visable from the intersection....and had me drive a big (6 kms) loop on a dirt road (with dirt road avoidance enabled) to approach the ferry straight on at the intersection I should have gone left at.
In downtown Vancouver, it is slow to update position and loses satellites often....the TomTom rarely does. Yes, I had both of them running for this comparison.
While sitting still at an intersection, it will change my heading direction, as if I am rotating in one direction....then the other........
Garmin customer service certainly was not much help. Suggested turning off off all avoidances....carpool, unpaved, seasonal, and u-turn is what was on. None of these should have been a factor anywhere I have had issues.....except maybe once it recalc'd after sending me through am intersection I should have turned at.....it might have had me attempt a u-turn during evening rushhour.
Yes, software and map was updated a couple weeks ago, shortly after I got the unit.

I sure wish TomTom made a motorcycle unit!
