Sorry bimerrr - my 'phone is a 6230i. I had exactly the same problems as you & was tearing my hair out for 3 days!! What eventually cured the problem was after pairing, when the screen said "Activate Phone" I removed the cell from it's cradle, switched it off, waited a couple of minutes then switched the cell back on - & PRESTO it worked..... May not work for you though.... Just try it. Rgds.
