The G35HVS is the one you want. Connect straight to 12 volts.

For use with PDAs, the new Garmin GPS 18 LVC is worth a look. Supports
WAAS/EGNOS, under 2 1/2" in diameter and 3/4" high, needs 5 VDC (but so
does the PDA), street price is $80US. Downsides are the fact that it
isn't available yet (1st quarter 2004), and has a non-removable magnetic
base, like just about every other cheap mouse-style receiver...
