The bt338 and GPSlim236 receivers by Holux are now shipping with Static 
Navigation turned off, as far as I know. About 7 months ago, they had SN 
on. Some resellers may have had old stock and that's why some of us have 
purchased a receiver with SN in the 'car mode'. SN is a feature that can be 
turned off by means of a program that is used by developers and 
manufacturers called SIRFDEMO. In fact, it's a piece of cake if you can see 
and know what you are doing. However, if you rely on a screenreader it's a 
'no go'. Basic communication with GPS receivers runs via NMEA messages, but 
there's a binary connection that allows for the fine tuning of SiRF3* 
chipsets. If you make a mistake in binary mode, e.g. you hit the wrong key 
while searching for the right menu, or switch the communication between 
your computer and the receiver off at the wrong moment, you're stuck with a 
receiver that's not accessible anymore. There's a work-around in that you 
take out the battery and wait for 24 hours, until the CMos battery has 
died. That resets the receiver back to factory mode and you can have 
another go. In short, don't do it if you don't have experience with this 
kind of stuff. Then again, if you know someone with good computer skills 
and a pair of working eyes, there's your solution. I've got the program 
here, and if you are willing to take a risk, just mail me and I'll send it 
to you. But don't complain when things go wrong.

The RoyalTec 2001 and 2010 have SN turned off and I also use the Adapt 
AD750 that comes with SN off.
