I was under the impression that when I added the 3.0 I was getting the newest maps. How/where do I get the latest maps?
No, Pioneer probably bought the maps for all their AVIC's at the same time rather than getting the latest and greatest when they came out with the 3.0 update like they ought to have. Your maps are actually from December 2008, my maps are from July 2009.
You can upgrade your maps yourself but it may brick unit if you do it wrong. You'll also be voiding your warranty. The instructions are so:
Download the map upgrade
Download the updated ezRider.exe
Download the updated license file
Unzip the files, erase anything to do with Puerto Rico and Mexico in the buildings\, poi\ and map\ directory. *
Copy the files onto an SD card (4gig at least so you can do the backup)
Boot into testmode.
Do a full backup on your AVIC
Pray to the Baby Jesus that you don't mess up
Delete the Building\, dem\, map\, poi\, speedcam\ directories in \Apl2\iGo\Content\
Copy the new building\, dem\, map\, poi\, speedcam\ directories for the 2009.06 update into their new homes.
Copy the ezRider.exe on top of the existing Apl2\iGo\ezRider.exe, yes overwrite.
Copy the license file into Apl2\iGo\Content\License, don't delete any of the existing stuff, it isn't hurting anything.
Cross your fingers and reboot.
Fin!
* I erased everything outside of the lower 48 US because my car will likely never go out of the country, ever.
