REFLECTOR: Navaid Auto Pilot with Porcine GPS Coupler and Panel Mounted GPS's

[Ron Brown]

I got a question yesterday about my Navaid Auto Pilot with Porcine GPS 
Coupler and Panel Mounted GPS's.

I got my Garmin 430 to work with my Navaid after getting Porcine's latest 
coupler update.  The problem is that most panel mounted GPS's do not 
transmit the NEMA RS232 data streams that are common to hand held GPS's - 
rather they transmit a data stream called "aviation".  The Porcine couplers 
have worked well with hand held GPS's but not "aviation", that is until the 
update that was made in 2004.  I got around to getting this update this 
summer and IT WORKS!  The aviation data stream will need to be set to 
"aviation - no altitude".
