Recommendations for satellite navigation for towin

I don’t think there is such a thing. You’ll probably either need to use the car's built in sat nav, or a stand alone one, or run an app on your phone. Personally, I’ve never found sat navs where you enter your vehicle dimensions particularly useful. An ordinary sat nav and a healthy dose of common sense does the trick.

If you check the forum (where this will probably be moved to), you’ll find several threads on sat navs. Parts and accessories is a good place to start.

Can you add Apps to your car system? If you can both TomTom and Co-Pilot have pay annually Apps that can be downloaded to the likes of phones and tablets so if the infotainment system in the car allows downloads they might work. In both instances they have a free trial option to see if they suit. The TomTom is just a straightforward sat nav app but the Co-Pilot has several versions suitable for larger outfits.
