FYI, I posted this also in the general forum discussion on Map update. I downloaded the new update yesterday and did the Quick install. The instructions recommended the Quick, and said they both install the same information.
The download and install went very well. I did not find any issues after install regarding media presets, etc. The instructions did say that all presets, and other map favorites could be erased during install. However, all of my saved information and media presets were intact. I will update further after getting a chance to fully utilize the new map.
