We have a Kenwood unit in our van (older one and I don't have the model # handy) and I will never do a combination unit again. Ours has worked fine, however, we have been unable to get it to update so the maps are way out of date. I've been in contact with Kenwood and they basically don't know what is going on, but it is out well out of warranty so there isn't anything they will do to help other than tell me what to try. We will have a standalone GPS from now on.
If you're trying to use map updates from Garmin, they won't work. The map updates need to come from Kenwood for some reason. I think it's because Kenwood pares down some of the information so it will fit on the internal memory of the Kenwood.
The only way I found to use a Garmin map update was to run it thru the Garmin utilities and create a custom map download which I then place on a MicroSD card for the Kenwood. This updated map can't be transferred to the internal memory of the Kenwood, but it can be accessed and used off the MicroSD card.
