I got a garmin dezl 760 full UK and Europe for 290 quid off eBay, it was 2nd hand the guy had used it just 3 times, and it’s immaculate. Had it for 3 weeks, so far so good. Easy to use and setup, type in your height, length etc and away you go. My truck is 12’ 4 high and it tried to take me under a bridge that was 12’ 6, but I didn’t attempt it. On the calculation was possible but it’s a bit too close for me
