I only had to make two adjustments:
1. When dialing by number, I no longer pause when speaking the numbers.
Instead of 931-555-8090, I just say "9315558090".
2. When dialing by name, I had to make some names into 2 syllables:
Instead of recording, "bob", I recorded "call bob".
Both seem to work flawlessly on my non-nav TCH.
