GRT Avionics

Well I finally managed to get a 12.1" display and smaller Hx display installed. I have a TRIG 22 that is controlled by the HXr. I have a Pathfinder ADS feeding in as well. Everything seems to be talking to everything else. Weather display is almost the same as the 396 I removed. Looks great!
A 430W and SL40 are installed but not tied to the GRT, controlled by a PMA 8000 audio panel.
I haven't been able to figure out how to remove the "Nav" control boxes in the upper right corner of the HXr display. I got the "COM" boxes out and the TRIG 22 control display looks like I want it to. I've been thru the SETUP menu without success. Can anyone help me out with this?

"NAV" boxes would appear if you have a serial port configured for an SL30 or have SL30 link settings enabled (in General Setup, Inter-Display Link).

Thanks, that fixed it. I hadn't selected SL 30 but I was sending commands on the inter display link. Looks perfect!!
