Could anyone tell me if there is a sat nav that has a truck mode that also has a live traffic service wether it be for an iPhone or a dedicated system ??

I notice there's a truck nav core for some of the tomtoms but is there any models which would allowe to install that and also have the live service ??

I have a budget of upto £200 So can't afford the full tomtom truck sat nav's

If you just want traffic you can by a TMC-RDS receiver for a 500 or 700 series and put the truck map on that, the best receiver I have found is the dual charger / receiver for the usb units, there is a company on ebay sell refurbed ones for £25 post free. New they vary from £50 to £80.
