Default VOR ?

Finally, there is some criteria that must be met - something like at least 2 miles outside the FAF, so if you get vectored in too close it won't switch. Frankly because of all the variables I recommend pilots get in the habit of switching manually. OTOH....
I have a 420W and an SL30 feeding a GRT HX EFIS. If I arm the ILS approach on the HX, then it searches all the nav inputs looking for a localizer frequency, and, at intercept, automatically switches from GPS (or heading hold, if in that mode) to the localizer signal.
Plus/minus between a 430W plus #2 com, or a 420W and an SL30:
Sl30 is a superior vor, actually two VORs or one vor/one ILS in one box.
SL30/420 doesn't put all your eggs in one box
430W/second com is about $1K cheaper.
What's a VOR ? You will use the 430Waas/GPS capability 99% of the time. The precision GPS approaches on the 430W are terrific when coupled to a TruTrak AP. Will put you (literally) on the 1000 foot marker every time. Better than an ILS in my .02. A 430W and the new Garmin Com would make a great combination unit. I have an SL40 and being able to monitor the 430W plus two other frequencies on the SL40 is really handy!
