Operation very simple and direct operational. BT and radio reception is nickel. The frequency change is very accessible, which is handy in long journeys where the spectrum free of any issue with the frequency fluctuates kilometers. No problem with my Galaxy S3 It's just a shame he does not send the song titles on the RDS radio. Certainly this is not essential, but it would be a nice feature (not having to take the phone when you want to know ...)
