Flew on Thursday and I didn't change anything since last Sunday's flight where everything worked great. I tried the same set-up yesterday and nothing worked. I kept getting a message that said it wasn't reading the vario data and then it couldn't read the GPS. Just locked up. I give up. Back to the old cable, Compaq PDA and Winpilot 13.01.

My setup is a CAI 302/303 connected to a V2 PNA running Winpilot PRO. I have been running this setup for awhile and have no problems. It communicates fine with the CAI GPS/wind information. I only have the programs/files I use, not anymore, loaded on the PNA. My storage card is used only for transfer of files, otherwise, its empty.
I have the brightness clicked down a few bars as the processor seems to run cooler and I also see no difference in brightness. It appears in this configuration I use less battery when compared to my IPAQ 3955. My IPAQ would lock up when I tried to fill its memory to the max. After that happened, I only used programs/files as I needed. Then I had no more problems.
The highest temp. that the V2 has been running in was when I was @ Hobbs for the 15 Meter Nationals. I had it baking in hot direct sunlight, running for 30 plus minutes, while waiting for launch. I would estimate my cockpit temp at the time was well north of 110 degrees F. I had no problems.
I might suggest to try to lower the brightness by a few bars and then only use the programs/files you really need for the area your in. Also, try removing/reinstalling Winpilot PRO again. Also, try removing the storage card and see if the problem goes away.
