Simple answer is no, many have tried all have failed

I used the on board sat nav(in the loosest sense of the word) to take me to Stoke last week and for some reason against my better judgement followed the directions thinking there may possibly be a better way than the route I have used for the past 25 years.
I ended up on a blind bend on what can only be described as a cart track wedged in by a huge lorry who presumably had a similar system installed and scratched my front NS wheel to f k in the ditch trying to extricate myself.
Had I had my Tom Tom on there is little doubt the route would have been restricted to roads wider than 12 foot  MY2011 HSE Santorini/Ivory/Piano Black/Privacy Glass/TV .Sadly gone.

If anyone ever manages to hack a Sat Nav CD so as to permit this, then everyone on the Forum will want to buy a copy, even if it is against the Forum rules.  In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures
Gone - A couple of RRS, A couple of Disco's. However thinking of another Sport.

i would imagine it could be done, my Merc e320 had the comand sat nav, and somebody hacked the disc, and added the tom tom speed camera warnings to it in a POI folder, then uploaded it via pirate bay. all i did was re-edit the speed camera warnings/accident blackspots etc every 6 months and burned a new disc, you just need somebody clever  07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater )))
