UPDATE:
I have updated the first post to include the link to the 523x firmware as I keep getting requests for it.
This is the usual 90/5/5 partition ratios with VIM, secret menu etc.
So if you are already running this partition scheme, your maps and music shouldn't be deleted.
As usual, have a copy of the maps DVD on hand should you need to reload it.
And the same warning still applies to older units with HW_radio version 003 or below: loading this newer firmware could permanently damage your radio board. If you really want to try and get RDS etc feel free to try, it does technically work.
As usual, any flash runs the risk of bricking the unit should something go wrong, so user accepts all responsibility.
