Thats one thing the other is when he says "do you want to start navigation" what are the options here ,ashavenot been able to fathom it out a yes or no option and what to do, trouble is I,m old.!!!!!!!
It's not cited as a specific, however it would be covered by s3 Road Traffic Act 1988, (as amended by Road Traffic Act 1991), headed careless and inconsiderate driving - essentially driving without due care and attention.
It's not, in essence, illegal to use your sat nav, however, if through doing so your attention is significantly diverted from the control of your vehicle, which in most cases I'd argue it would be, then you may well be guilty of said offence.
Also, just as a note, although police radios can technically be used, you are taught not to use them unless necessary, as like most things when driving it causes a distraction.
Tuning your radio is noted as an example in the legislation of actions that can make one guilty of an offence, the others would be arguable as being necessity in driving with the exclusion of the windows, IMHO.
