Check into the 480's unique capabilities before you decide. For example, the 480 can recall a bunch of recently used frequencies and monitor the stand-by frequency when there is no chatter on the active. Great for ASOS and ATIS pick-up and traffic monitoring when you're still talking to ATC. There are probably lots more features that I can't recall right now so if it were me, I'd still go with the 480 as the primary communication box.

Since I have both the GNS480 and the SL-30 I've thought about making the SL-30 my #1 (primary) nav/com. Then the backup #2 nav/com is a full moving map 480 system. This would involve moving the 480 to power buss #2 and the SL-30 to buss #1 but that's not a big deal. Thoughts? Robert M. Simon That is exactly what I'm doing. The SL30 is my #1 NAV/COM and the 430 is #2.
