Does anyone know whether the HU assembly for the 09 Sport will fit into the Base model? If it will, I’m giving mine away to anyone who will come to where I work in central Long Island, NY to collect it (sorry, I won't ship it). Of course, anyone who wants it even if it doesn’t fit into the Base can have it too, although I assume that the only reason why someone would want it is so that they can have USB, etc. in the Base. PM me if you're interested.

 

The HU themselves are the same in Base and non-Navi Sport.

The USB can be added to the Base without replacing the HU. I'm not sure what the "etc" is... but chances are good, probably no different from the USB, added without replacing HU.
