Right, and I've been using Nokia-Sports-Tracker for nearly 2 years now.

No, I own a very small BT-GPS-module which runs with an
AA-Battery/Accu. The reception is very good, although not SirfIII.
Best results in the car at the front window, and while walking:
on top of my head ;-))

meanwhile the On/Off-switch (cap) has broken, the module felt down quite
often. But it still works, I have to fiddle about for switching on or
off.

It has a cable with a USB-plug that can be plugged into a Car charger
(both included, not for loading the accu, but for running the module).
The other plug is compatible with chargers of older Nokia Cell Phones.

Best Regards
