I tried this route:

KEWR DCT RBV J191 PXT J14 RIC J165 CHS J174 MILIE J79 BEENO J103 OMN DCT KDAB

and selected an RNAV approach. Bad Idea. I eventually gave up and selected an ILS approach and succeeded.

Like Dave, I would stick to ILS approaches or a visual. They are lot easier. RNAV approaches don't appear to work. This was my first, so that doesn't hold up too well. LOL.
