They are not that new!.
Hgv drivers must be aware of the 40 limit on single cariageway roads and that there are ways of detecting an HGV. I would not gamble on any type of cameras capabilities to detect the size or weight.
If you want a cheap basic level sat nav including camera locations I can reccomend the navman f20 £130 from argos. It works streight out the box. It can work 3 hours without being recharged. It is very easy to use. It has a clear/loud voice that I can hear. You have very little need to look at it. as a result I had good instructions before I even saw the roundabout signs and a stressless trip across tricky roads I did not know
