A couple questions...
1) Does a GNS-430 have DME built in? i.e. If I don't upgrade the GPS DB
can I still fly a VORDME approach off the 430's VOR? (I'm trying to
decide if I should keep my DME)

There is a slight advantage to keeping your DME, and ADF if you have
one. If you need an alternate, and the alternate only has non GPS
approaches that need either a DME, or ADF, then you can't legally use
the alternate unless you have the necessary equipment in addition to
your GPS.

At least that's how I understand it.
