When you say it didn't load any nav data what do you mean?

I have that a/c running in FSX and I had one problem that when I entered waypoints and completed the flight plan it would not associate any altitudes or speeds with the waypoints. With no altitude data it did not calculate a TOC and TOD. I found, unlike the Level_D FMC, you must enter a "Reserve" fuel percentage before it will calculate altitude/speeds for the waypoints.

Dear colleague. I suggest you proceed to re-read the manual carefully and FMC aircraft operations Manual. Once you are clear on those two items. He will make easier the operation to use the FMC system and thus the B732 aircraft. Of course, where we can help you be the information that will try to make things easier, as long as the request is well explained.
