Captain Panik 22

I am using the 172 and the B58. I load my flight plan. Once airborne I engage the AP with HDG and everything is fine. The ALT is working as well. There are no DIS or ETE numbers displayed. I engage NAV and then the FPL disappears and is replaced with the following…+45-75. The 530 stops tracking along the route. HDG still works. I am at a loss. Everything was working fine. I updated to the GNS 750. I also upgraded air manager to the 4.0. BTW all my testing was done with out the AM running. thanks for the help in advance.

The issue ... after installing the GTN 750 i opened it up into the AFL king air 350. Two panels. I chose the master for panel one and etc. it worked great for a few flights. Then one day it was just black screens. I went into settings and what appeared down the left column were red pad locks. I have uninstalled the program and will try a reboot. Do you have any information about the red locks. thank you

Has there been any resolution to this issue. I am having the same problem.

Ok this is where im at. FSX Steam and FSX on computer. I have 3 Saitek panels, ( radio, Auto pilot, multi switch), I have Cessna trim wheel, and CH rudder pedals (soon to be replaced with Saitek RP). My troubles began when I decided to download some sweet airplanes I have seen on other simmers YouTube videos. Also the EZDoc Camera, this was my first download. SOme down loads worked some didn't, no matter what I tried. I wanted to get more involved with the setting up of some of these add-on airplanes so I bought the FSUIPC manual and program. They suggested that if I was having trouble with the Saitek panels to use a program called SPAD. I did. And with some tinkering I got everything to work. I read an article that said that I could now deleate ALL Saitek files and I did. Then the next time I started the sim nothing worked. I am wondering if I should just uninstall everything and reinstall it. What say you?
