I share my hangar with some guys who did a good job building a GlaStar. They are trying to program their GRT EIS 4000, and need a bit of help. GRT has not responded to their calls and messages. Is their someone out there in the RV group that understands the GRT logic and might be able to help these guys? They have inadvertently deleted one page, and would like to get it back or re-populate a different page, and they would like to move a parameter from one page to another. If you are good friends with the GRT EIS, please send me a PM and I'll help them connect to you. Thanks!
