GPS- which one for caravan, 4WD and city?

I am led to believe that the VMS is compatable and not a nightmare. Ours is a bit older now (touring 3000) but it was plug and play and all the multimedia (CD/DVD/Radio/USB etc etc and blue tooth to the car system) And most importanly, OziexplorerCE compatable. Don't use the street nav (Igo) so I wont comment there. Tossed moving map out (deleted it). Prefer Ozi. Don't like stuff like laptops and tablets floating arounmd the car. Even the mobile phone is stuck back at home. We prefer to have everything bolterd down and installed in the dash so its harder to steal and is not a projectile in an accident of on a rough track.

But there must be a cheaper one than the VMS with all that. Ours is not portable so I think the VMS is wrong for you as you want a portable one for hand use.

I was just addressing the comment about the nightmare integration in the Toyota.
