I need a GPS for my bike

Bicycle that is. I need a GPS and want your ideas on which one to get. What I need it to do is the following.

1. It needs an earphone jack so I can hear it while riding on my bicycle.
2. I need to be able to program a route into it via my computer USB.
3. I would like it to be able to say the street names.
4. Have a battery life of 3+ hours.
5. I'd also like to be able to mount it in my car and use it for car road trips.

Do you guys know any that fit this bill?

I got a TOMTOM XL330S. Not very happy with the programming though. If you don't hold your head just right, the thing bails out and the tech support is friendly but not so smart. I am on my 3rd one in three days. I would blame it on myself but I followed the directions to a "T" and it still bailed out. I will have the tech support on the line this time before I even turn it on.
