Which GPS Support LNAV/VNAV?

As I understand the new RNAV approaches support three types of approach:

Lateral-only navigation (Basically the traditional GPS approach?)
LNAV/VNAV
LPV

Now, IIRC, only the LPV approaches *require* WAAS, while the LNAV/VNAV
approaches support use of barometrically-derived *or* WAAS VNAV guidance. I
understand that baro-VNAV is a common function of FMSs, but are there any
panel-mount GPSs out there (beside the CNX-80) which can provide this type
of vertical guidance with the necessary RNP?
