Mr Brunstrom described his radio experience as "very worthwhile"
The chief constable of North Wales Police has co-presented the Jeremy Vine Show on BBC Radio 2.
Richard Brunstrom was the first in a series of "significant" figures to join Vine on the two-hour programme.
The choice of music included The Clash's I Fought The Law and Elvis Costello's Watching The Detectives.
Mr Brunstrom took calls from listeners on subjects ranging from drug use, the BNP, the banking crisis and a cull of thousands of grey squirrels.
Mr Brunstrom opened the show with what he called an "appropriate" song - I Fought the Law by The Clash.
He also joked: "My career's at a pinnacle - my own jingle."
Mr Brunstrom said he had enjoyed the experience which had been "very different" from his usual daily routine, and a "very worthwhile" exercise.
At the end of the programme, Jeremy Vine asked Mr Brunstrom - who has been dubbed a "mad Mullah" for his hard-line stance against speeding drivers - whether he was happy with the way he had been portrayed in the media.
Mr Brunstrom said: "I think I have been very accurately portrayed actually."
When asked about the "mad Mullah" tag, Mr Brunstrom said he made no apology for trying to make roads safer, adding it was a "badge I almost wear with honour".
A successor is being sought for Mr Brunstrom, whose North Wales Police contract expires at the end of 2009.
