Mike -

Ron & I had some of the same conversation wirth Tru Trak on Tuesday. The  
DFC 250 will not be able to handle the GPSV for two reasons. One is that  
the 480 will not send it - for the time being. And that is in Garmin's lap  
to work - as you were told. The second reason is that the computational  
power and memory in the 250 will be probably be over run. They said they  
never did promise that the 250 would be able to do it. The Sorceror has  
the computational and memory capacity and only needs the solution from  
Garmin. The real shocker was when we asked if we could trade the 250 box  
in for the Sorceror. The answer was yes - it uses the same pinouts and  
tray. However, the cost will be $4600!!! :-((

For the time being, we'll use the vv input to the 250 to fly the GPSV and  
let the box take care of the courseline - that is, if we ever have to use  
it to get into a field that only has WAAS for an approach.

The IMAPS Group had a stunning combo of a tablet PC (Motion 1400),  
approach plates, sectionals, IFR hi and low charts, GPS moving map, Blue  
Tooth GPS, Destination Direct software, Aeroplanner software and Weather  
Worx weather. Getting the WxWorx receiver with Blue Tooth is an option.  
Annual update fee, on a 28 day cycle, for the plates, sectionals, enroute  
IFR charts and other software is $200.  If anyone is looking into weather,  
take a look at this package. The tablet PC is complete with stand and  
keyboard (built into the hard cover top). It has a 40 gb hard drive and a  
1.1 gHz processor and 512 Mb of RAM. One can use it as a full-up laptop PC  
when on the road. Check it out.

Count Ron and me in for the ES Fly-In next year @ LAL.

Best,

John
