Changing the flashcode won't help... you'll need to have the radio sent to Motorola for an uplift to IMBE. The vocoder must be flashed to make IMBE work.

If the old one has "astro" modes in it then its version of astro is VSLEP. The new one has "astro" of IMBE. Two different types of Astro. VSLEP was motorola's 1st shot at Astro and IMBE is the APCO25 standard from what I know. VSLEP and IMBE will NOT talk to each other in digital mode.

D'oh... posting too early in the morning again. Got my new and old flipped.

Jason's correct... if the old one does digital, it's VSELP. You'll have to get IT uplifted to IMBE to be compatible with the new unit.
