This lists three different part numbers for them. Dunno what part numbers go with what years though.

Note that the eMap is discontinued, and it's not waterproof. (Though, if it gets rained on, and you dry it out good, it'll be fine.)
Having said that, I have one on my dirt bike and like it. I have a StreetPilot III for the car/truck/street bike.
I may be wrong, but if the battery is completely dead, there won't be power to "prime" the FI (the noise you hear when you turn on the key), so it wouldn't bump start anyway. Right?
