Hi, I have an XRX linked to a Garmin 430 and must report that quite often, opposite direction traffic does not show up, even with the furthest range and altitude settings. ATC will advise of a target within 1000' of my altitude and it doesn't show up. Sometimes they do show on the XRX, but not as reliably as other slower (relative speed) traffic.

I have the XRX mounted on the middle of the glare shield as far from any obstructions as possible.

Suggestions?

Thanks.
