Don - as you know we both went through the HK retrofit which initially was very cool, but eventually caused both of us headaches when our HK units went bad. Before I gave up on the HK unit and went with the Sony/Hawgwired conversion, I tried to get info from HD dealers, the MOCO, HK and local electronics experts regarding repairs to the HK units. Basically, there is no repair facility available to the general public, unlike the Radio Sound which manufactured and is still repairing '05-older HD radios. Now, if your HK goes belly up and it's under warranty, it simply gets replaced. If you are out of warranty, you can receive a refurbished unit through your local HD dealer. Dealers in the Milwaukee area were quoting between $200-400 for the refurb radio, plus labor to yank the old and replace with the refurb. Hard to believe a $1000 radio is pretty much a disposable item. When you think about it, the HK radio is about the biggest scam HD has ever pulled off. CVO Ultra owners get the NAV, CB, XM and Amp which really is one the the bike's biggest values, especially if, for example, you've got a bike that came only with the base HK radio. If you want to upgrade and add all the peripherals, let's see...NAV $1000, XM $500, CB $300, High Output Amp $400 not to mention the various interface cables, switches, etc. Even at 20% discount, you're still shelling out $2K in add ons. I admit to being at the head of the line holding a sucker sign, but man...this is one Harley program that is really, really bad. I wish Hawg Wired had come out with the conversion long before I started down the HK path. PJ
