got my shiny new tuner yesterday (thanks eutronix.com) and for some reason, doing a long press to scan the frequency doesnt work.

This is a reported bug in 2.0 final. I hope we can get a 2.01 at some point soon, although I don't know if this is planned or not.

In the meantime, you must use presets and the direct entry of frequency numbers using the remote control.
