Probably LNAV+V, wouldn’t bet my life on it though without reading the manual.
standardtemp2383@reddit
need waas for +v
Twarrior913@reddit
Not for +V, +V is just VPTH or the equivalent, advisory.

No you don’t. +V is advisory vertical guidance. You do need WAAS for V though.

To my knowledge it would go to LNAV minimums. Garmin 430/630W can go to LNAV/VNAV minimums (though not very common as LPV minimums are almost always lower), but LNAV/VNAV also requires WAAS in this case (unless you have a barometric altimeter for baro-aiding). Thus, losing WAAS looses both LPV and LNAV/VNAV, resulting in LNAV.

Most likely would switch to lnav mins with some sort of visual cue. But again read the manual

Read the manual

The 430 I fly does not have baro aiding and automatically downgrades to LNAV minimums.
Also obligatory read the POH or the avionics supplement/pilot’s guide in your plane.
