I also had the GPS V. Really a great unit. The only issue (for me) was the 19MB storage and map transfer through serial.

I travel a lot to areas out of reach of the 19MB. This means that if I were going from NY to Boston, I would have to drop some maps inbetween the two end points. This is not so terrible since there is a base map built into the unit that will display major routes (such as interstates) when there is no detailed map present.

Anyway, I recently bought the Street Pilot III. It is also excellent and solves the problems with the GPS V. It has 128MB of removable media and USB map transfer. Garmin just came out with a newer version of the SPIII which uses compact flash as its map media and has a wireless remote. Street Pilot 2610
