Dear Sir I have the CD version of the B737/700 and I would like to upgrade it to the version with the TCAS system wich I think is the B737/800. Can you tell me how can I do it? Thank you for the excelent panel and I can tell you that because I am a pilot, keep up with the good work

In my case I purchased the 800/900 CD. This also upgrades the 600/700 panel and a few other things. I also think it enabled some additional FMC functions that were described in the FMC manual for the 700 as not implemented yet.I purchased both CDs at the same time (Aerosoft version). On the Aerosoft site you can find a specific procedure to follow and a service pack for the CD. When installing the 800/900 after using the 600/700 for a while you must follow the instructions in the FAQ/Support on the Aerosoft site.I purchased both to have the full featured panel and I also had use for both the 600/700 and 800/900 variants for the airlines I simulate.

Thank you for your reply I will do that you very kind happy flights
