I've been looking for a place that fixes HD radios for a long time with no success, but finally I found what we all need.
I just came across http://www.ironcrossaudio.com/
and they will fix any Harman Kardon HD radio for a flat fee of $250.00, this includes software update, a one year warranty, and a lifetime re-repair discount should you have any problem after the warranty expires.

After calling a large radio retailer and reading online reviews I am afraid to install an after market radio even from the marine section after I notice multiple HD owner complaining about how quickly these units started to malfunction due to water exposure. This led me to look at online sales of used stock radios but you really don't know what your getting until it's installed in the bike, so in most cases if there is a problem you only have 14 days to install it, then find you have a problem, remove it and send it back for a refund. I know this is a worst case but I'm sure it happen more often than we think. From the little research I've done it seems a lot of the radios are different from year to year despite the fact that they look alike in appearance. So this place seems like a good bet as from their own web page they claim to be former HK techs and who could no these radios any better.
To the moderators of RD.org, I think this would be a good sticky so new comers could find help for their stock radios and feel free to rewrite this as you see fit as I'm not sure you'll like the prices noted in the article but it didn't make much sense looking at it after I removed them.
