FAQ: 

Will this system work with my In-Dash Car DVD? 

Yes. If your current system has an RCA camera input, and a trigger line input (used for sending power from the reverse lamp to the stereo), it will work. 

What are Tyre Pressure Monitor Systems?

Passenger vehicles in the 1980s and today are a mandatory feature in the United States. 

Benefits of a Masten TPMS?

The dynamic behavior of a pneumatic tire is closely connected to its inflation pressure. Key factors like braking distance and lateral stability require the inflation pressures to be adjusted and kept as specified by the vehicle manufacturer. Extreme under-inflation can even lead to thermal and mechanical overload caused by the overheating and subsequently, sudden destruction of the tire itself. Additionally, fuel efficiency and tire wear are severely affected by underinflation. Tires do not only leak air if punctured, but they also leak air naturally, and over a year, even a typical new, properly mounted tire can lose from 20 to 60 kPa (3 to 9 psi), roughly 10% or even more of its initial pressure.

The significant advantages of TPMS are summarized as follows:

Fuel savings: According to the GITI, for every 10% of under-inflation on each tire on a vehicle, a 1% reduction in fuel economy will occur. In the United States alone, the Department of Transportation estimates that under-inflated tires waste 2 billion US gallons (7,600,000 m³) of fuel each year.

Extended tire life: Under-inflated tires are the #1 cause of tire failure and contribute to tire disintegration, heat buildup, ply separation, and sidewall/casing breakdowns. Further, a difference of 10 lbs. in pressure on a set of duals literally drags the lower-pressured tire 13 feet per mile. Moreover, running a tire even briefly on inadequate pressure breaks down the casing and prevents the ability to retread. It is important to note that not all sudden tire failures are caused by underinflation. Structural damages caused, for example, by hitting sharp curbs or potholes, can also lead to sudden tire failures, even a certain time after the damaging incident. These cannot be proactively detected by any TPMS.

Decreased downtime and maintenance: Under-inflated tires lead to costly hours of downtime and maintenance.

Improved safety: Under-inflated tires lead to tread separation and tire failure, resulting in 40,000 accidents, 33,000 injuries and over 650 deaths per year. Further, tires properly inflated add greater stability, handling and braking efficiencies and provide greater safety for the driver, the vehicle, the loads and others on the road.

Environmental efficiency: Under-inflated tires, as estimated by the Department of Transportation, release over 57.5 billion pounds of unnecessary carbon-monoxide pollutants into the atmosphere each year in the United States alone.
