Since you are the first user to have done this (OEM->Sony OEM interface->Tuner), it's going to be fun diagnosing this one.

For starters, go into Emplode's "configure player" screen and try setting the stalk to the opposite "handed-ness" of what it's currently set at. For instance, if it's set to left side, set it to right side.

Let us know if that works. If not, we'll start looking at other possible issues.
