Velocity XL Center Screen Blank

[Pondimus]

Hi, I just purchased the Velocity XL today, and after having turned on the avionics, the center screen is blank. I think I must be missing something really obvious! Any ideas? Thanks!

Sorry I didn't see this post for a while. You may have posted it before we created the general Black Square category on the forums. That center screen is a GTN 750. It should come on if you have either the PMS50 GTN 750 (freeware or payware), or the TDS GTNxi (payware) installed. The free GTN 750 can be obtained here.
