I had the same EXACT issue. I even took my Vista CX back and exchanged it for another Vista CX and the results where exactly the same. I tried all the different suggestions Garmin's tech support gave me as follows:
These did not help at all. I also updated to the most recent firmware for the Vista CX figuring they may have fixed it on a newer release. But again this did nothing. My thoughts are that there is still a firmware issue that Garmin will possibly find eventually but needs this kind of information that the video shows. Great Job documenting this.
As for me I could not deal with this consistant problem and ended up taking it back and ordering the 60CSX from Amazon. Since the Vista Cx cost me $350 at the local store here... the extra $50 to upgrade was a no brainer.
NOTE: if you buy the 60CSX or 60CX do yourself the favor and run the webupdate software as soon as you get it, they have really tweaked alot of old issues... and apparently where I live the WAAS is tough to get do to my location but I have been getting the 'D's on at least 1/2 of my satellites.
So if you can sell your Vista/Lengend CX I would highly recommend getting the 60CX or 60CSX as its replacement.
