Satnavs

Probably a bit early for me to be looking already but ill ask the question anyway.

Assuming im driving a LGV early next year and i am not that well traveled around the UK.
Im going to be on the lookout for an idiot proof, large screen, lorry compatible sat nav.

Are they 24v or is there a gadget that plugs into the ■■■ socket to reduce it to 12v?

What do you recommend?
Price not really an issue as i have time to save.

Cheers Rich
