I would start mentioning to the dealer about the Consumer rights Act, and the Sat Nav system as supplied being 'not fit for purpose', and thus rejecting the car under the aforementioned CRA - unless, of course, the dealer wants to provide, free of charge, the updated SD.

That might just get their attention - your contract is NOT with Ford, but with the dealership. THEY are responsible.

I had three cars with built in SatNav before my current car. They were fine and I used it a great deal. I did not want a Garmin or Tom Tom. Its another piece of stuff to get stolen.

With the current car, I have discovered phone based Nav apps. Perfect. Can't get stolen as its in my pocket wheen I leave the car. Always charged and always up to date (thank you Mr Google) and excellent traffic information with dynamic route guidance (thank you Mr Waze).

For the first time, I dont really need built in SatNav. And the alternative is free save for a bit of data.

Got a navigation app on my mobile called NavFree which works great and is (like Google Maps constantly updated free. But as I understand it Google maps uses data to load maps as you drive whereas NavFree stores them all on your phone when you install the App meaning no network connection is required.

Hopefully it will work with SmartLink on the new motor.

Phone-based satnavs may become useless as you go further into the countryside, just when you need the satnav - fine by the motorways and main roads, ie when you don't really need a satnav.

At least with a stored map you're ok until you get back to civilisation.

That is exactly why I like the NavFree app. You are not reliant on a phone or data signal, only a GPS signal (just like any satnav).

When you download the app you get one countries maps free which for the UK and Ireland takes about 500mb. Mine are stored on the SD car in the phone so no impact on the OS.

Work colleague was going to the states on a road trip from Chicago to New Orleans. Down loaded Navfree with the maps she needed (did not do the whole US because of the file size) and had no issues, worked perfectly. More than can be said for the car hire company, booked a Mustang and got a dodgy Chrysler which considering she drove a dodgy PT cruiser was a disapointment.

The law is simple : it is illegal to use a hand-held phone or 'similar device' whilst driving. 3 points, £100 fine penalty as standard.

For any built-in device - or a phone in cradle, two-way radio, etc., if the police think you are not in full control of your vehicle, or not paying attention to your surroundings, then you can still be stopped and charged/penalised on other basis.
