Dogbreth,
I have been involved in GA and electronic manufacturing for over 35 years and the situation we are having with Sagetech is one of the saddest experiences to date! I have not had the system shut down on me after the window mount work around, but I have never used the wall wart to power it. I think they state in the ops book that there would be issues in doing so. My suggestion is fully charge up the SV with it shut off and give it a go. I have had very good battery life (in excess of 6 hrs) so far.
Regardless, I am way less than satisfied and will probably list it for sale on craigs list and or barnstormers. I am currently looking at the other options and may travel to Sportys tomorrow to look at what they have to offer.
It is really a shame that we are struggling to get a device that is suppose to offer us safety and data to avoid problems to even function as stated by the manufacturer.
I do not hold AP responsible and thank Walter and crew for their willingness to muck through the issue with us and try to find a resolve for the problem.
Hang in there, we are not alone!
Paul
