Thank you for your advice. Followed your instructions and reinstalled to the Parrot Minikit slim the corrected phone list. Naturally I then tried some sample voice activated dialling. The results were that the Parrot recognised the names OK but about 50% of the calls attempted I could hear the dialling tone but was not connected. I tried deleting and reinstalling the phone list again with the same results.
I found on the second try with the voice-activated dialling the connection was successfully made. Needing the Parrot to use easily in the car, having unsuccessful connections is a little disturbing as the safe driving aspect is important.
Having read several posting on this forum I realise that many people do experience various problems unfortunately. I wonder if you or anyone would care to comment on this aspect.
