This nuvi features exlusively points of interest and location information from NTTS (National Truck & Trailer Service) Breakdown, in addition to lane assist, subscription-free traffic, speed limit indicators, Bluetooth and text to speech. At present, drivers carry around a phonebook-like directory with this NTTS Breakdown information – the latest nuvi now provides driver’s that information with just a tap of the screen.

The pre-loaded NTTS database includes long-haul focused POIs, such as truck repair, towing and recovery, tire sales and repair, glass repair, fuels stops and more.

The nuvi 465T includes free lifetime traffic service (no word yet if it will be ad-supported, as the current 2x5T and 7x5T models are), and will also display warning information of upcoming road conditions to help aid driver awareness of possible truck hazards along the route such as sharp curves, steep grades, road narrows and more.

“High resolution 4.3-inch display that is easily read from the driver’s seat of a long-haul vehicle.” is what the 465t will feature as stated by the Garmin’s press release. That’s the same size as Garmin’s current wide-screen GPS devices, so it’s unclear if this will be a higher resolution LCD or not.

Suggested retail price is $499. Available in the second quarter of 2009.
