Jim,

Thanks for your kind offer. I assumed when I posted that the PC interface
would include a little dongle with buffers, converters, and whatnot. I didn
't realize it's just a cable. I've homebrewed innumerable computer cables
so I should be able to manage this.

Thanks for the pfranc lead.

I'm a bit confused though about their instructions and the business about
the computer port not being able to power the Garmin. For just a database
upgrade, can I let the batteries run the GPS and just ignore the power
issue? Should I just make up the cable with just the data wires?

I'll probably figure this out when I study the pfranc site some more but any
clarification would be appreciated.
