I'm probably going to return my PN-20 within the week... (Those wanting to purchase might want to wait - possibly-a firmware update is supposed to be in the works for mid-April) It hopefully will clear up a few naggling issues I experienced. (at at stand still, the odo, speed, and alt were all over the place). It showed me at 16,000 ft at a speed of 124 mph. One other thing that bugged me was the 20 showing me 100 feet from the road I was traveling.. When I ventured some distance away, other roads were spot on. (this may be a GPS wide issue anyway) If I had the time to wait for the firmware update, I would have. But these issues all together were too much.. These bugs get fixed and I think the autorouting will be solid..
That said.....I liked the software and had no problems with a 1 gig card I bought and read thru my front panel of the HP.. Transfers worked fine too.
I'm wishing I waited 1 more month before my purchase, but thinking I'll have to check into a Garmin 60cs or Magellan 500.
