Warning, the new RHB Garmin Navigation graphics are not as nice as the original. Some mid to late 2012 builds have them already, and there are forum threads regarding this.

No comment in the TSB regarding the poor album artwork software (Gracenote) that will not recognize any mp3 albums downloaded via thumbdrive, or about 20% of albums downloaded directly from the original CD.
Album Art for 430N
I am still waiting for a Gracenote update, since my RHB will not recognize any new CD's released since the last (April 2011) Gracenote update. I won't hold my breath however.
Also, no fix for the A-Z search function that will usually (not always) only allow the entry of the 1st letter of what you are searching for. Not great when I must have 25 albums that start with the word "The". Other times it works fine and lets you type as much a you wish...
Searching for song on HDD - No "A-Z" option?
Waste of a TSB, if you ask me - when they did not address all the issues and might make some things (Nav) worse for some people.
