Fourth posting on Friday... back being on organic flyer?

I got the battery and went to the internet to get the CarminGPSIIPLUS manual, got it but after sitting in a glider for 20 minutes, I gave up. It did not make any sense what so ever. I really need somebody just to give me some idea. I will ask around. LNav was even more defeating. I absolutely haven't got a glue. Must I go back to being organic glider pilot? Organic glider pilot is somebody who just flies without any modern aides. Just with the broom.
