Best SatNav for a lorry driver?

[mp3boy]

My gf's dad has just got a new job delivering toilet rolls all over the country. He's been driving lorries for a while but up to now it's been fairly local.

He's asked me to find out if they make a satnav specifically for lorry drivers, that won't send him down country lanes and under low bridges.

Any info would be appreciated.

Cheers

There's no sat nav specifically for HGVs but he could use a Tomtom and put the low bridges on it, when using a sat nav in a truck it should be used together with a map, follow a sat nav blindly in a truck and you can expect problems ;)
