Yesterday I updated the maps and went for a drive with navigation routing set to Automobile Driving with lock on road ON (see screenshot for GPS settings), the result is that the device now gets confused and will usually recalculate and lock on adjacent roads that run parallel or near the road you are driving on making navigation unusable.
For example on a 2 km stretch of straight road segment where I am proceeding on, it would think that I have deviated several times off the route sometimes on roads that are as much as over 50 metres away from the one the car is on. As a result on this 2 km stretch it recalculated about 7 times despite no change of direction.
I will post a link to a youtube video when I get the chance to show the flawed behaviour of my updated unit side by side with the proper behaviour on my other unit. My other unit has the old maps and old GPS chipset firmware and is rock solid in navigation.
I really think there is something seriously wrong with these new maps (I also already posted about the thin graphics style earlier on) or possibly GPS chip firmware.
Please let me know if you can also reproduce this (please see screenshot for routing settings). ciq.forums.garmin.com/.../1340645.jpg
