Thane11, when I enter 2011 EX-L it says the latest version is 4502 and when I look at my car it says V 03249. I was thinking of downloading the 4502 version to CD and then load it to the car as the site suggests but don't want to screw it up as everything seems to work good now. Have you done this procedure without problem?--DaveFirst check to see that you have the most current update for Gracenote. The current version is v121. The Official Honda Site for Gracenote Updates
Second, check with Gracenote support Gracenote | Gracenote FAQs
Finally, if that doesn't work, check back next month in April 2012 when the new update comes out.
