We're working on the radio and have some improvements which should appear in the next beta: however, the radio quality is always going to be limited by the fact that there's a 220Mhz CPU about an inch from the tuner - something most car radios don't have to contend with...

As for the antenna plug on the cage - feel free to remove the existing one (it's screwed on) and fit your own. The next batch may have a euro connector, we've not fixed on this yet.
