Hi guys...

The hubby has a 2008 GW w/navi. We sprang for the latest greatest map with gupdate.gcd date of 1/13/2012 (I assume that is 4.6). The Hubby installed it but the map which says 2011 but is really a 2010 map.

The thing is the Map is glitchy as all get out. The streets jump all over the place when you turn a corner and even worse when you set a route the whole thing blinks on and off. We have tried 2 different Cards. I'm thinking its bad firmware or a bad map.

Ideas? My first step was going to be to try a newer map...I actually own another Garmin so I have a gmapprom.img but that is only the Western states.

Garmin seems to be great at Maps but are horrible with software...I always have issues with there software for all of my devices.

As a follow up the bike works just fine with the 2012 map update (with the noted exceptions of the POI search). So my guess is the Map files on the cards being sold by Garmin are corrupt. The issues we were seeing were reported in Mid-2011. Garmin stopped shipping cards until the issue was fixed. Looks like the issue is back. Will likely never buy another GW with a Navi system.

I have a Zumo on my HD and while I still have problems with it blinking out once in a while I can load routes...the husband cannot load the same routes so his is useless for being able to lead on a trip.
