The 200W the OP and I have hasn't had its firmware updated from version 4.00 in almost four years. This original version of the 200W uses the older interface with + and - signs in the upper left and right corners. Garmin, in a brilliant moment of confusion, decided to re-release the 200W for 2009. This unit externally appears like the old 200W, but has the firmware and interface of a 205W. Comments about no longer having the 2GB limit per map may not apply to every unit.
