Navman 4100 or Emtac Trine II

[gjp]

Hello

pretty new to GPS world.

I have a IPAQ 4150 that I now want to turn into Sat Nav system.

I'm thinking either Navman 4100 or Emtac Trine II.

Both I believe are Bluetooth.
I know the Emtac is pretty new, any one got any ideas which is better ?

Also - not sure what software to go for - is TomTom 3 any good (seems to get mixed reviews in Forums)

Thanks

Emtac say you will get around 10 hours from their receiver whereas with the Navman will get you about 20 hours. I haven't used the Emtac but I suspect they will both offer the same performance so It may come down to battery life versus cost.
