Tow car SAT NAV for caravanning use?

Towing doesn't occur to most car manufacturers & most car buyers, so why would an integrated sat-nav have a towing option? Just use the factory fit system with a little common sense & forward planning.

They are about Del, cos most of the big supermarket delivery drivers have em to keep clear of low bridges and weight limits, I'm sure Ive seen them advertised in caravan magazines from time to time..H.

I have a 3 mths old Kia Sportage 2ltr Gt Line and you’ve just answered my question before I’ve asked. I’m going off in 2 wks and was wondering what they’re like for towing. My last car was the Nissan Xtrail  09 plate and was brilliant would’ve towed a tank.  Ive always used the onboard sat nav but always check it against a map. They’re good but not infallible.

SatNavs have had their problems since John Constable captured an embarrassing moment down at Flatford.

I have a Sorento kx3 and I use the inbuilt sat.nav.when solo and my garmin/avtex unit when towing.Neither are infallable so use maps etc as well!Incidently,I find the Kia,s instruction to "leave the exit" really annoying!

Does the mapping that your sat nav uses include road width data? If it doesn’t then it is inevitable that your tomtom-garmin will send you down an unsuitable narrow road at some point. I believe but stand to be corrected, ordnance survey made this data available to sat nav makers at the end of 2016 (at a price)
