Does anyone know when and how often there's an update for the Kenwood GPS DVD (KNA-DV4100). I have the 2004 version, but wondered if they have one every year. Also, any idea how much the updates are, and where to purchase them?
There is a new disk coming out around 02/28/2007. The part number is KNAMP416 or possibly KNA-R3000. Not sure of the price, but I'm sure it won't be cheap.
