Features

Heavy Duty: Jensen Heavy Duty series head units are specifically designed, built, and tested to withstand even the harshest road and work conditions, such as humidity, electrostatic discharge, vibrations, and temperature fluctuations. Its entire front panel is an impervious membrane, preventing dirt and grime from accessing the control panel through pushbutton gaps. The head unit's conformal coated PCB board and heavy-duty design specification provides maximum durability under all conditions. The following tests are performed on Jensen's Heavy Duty in-dash receivers.

• Extreme Temperature & Humidity Test: Tested to ensure that the unit will fully function in -22° F to 158° F temperatures, as well as up to 95% relative humidity.
• Vibration Test: Tested to withstand 4G's at 20-500Hz for 9 hours to ensure the unit can withstand the extreme environments most commonly met in heavy duty applications.
• RF Performance Test: The RF Chamber test ensures that the stereo keeps clean signals in and the bad signal out, so you are always left with a steady signal without outside interference.
• Electrostatic Discharge Test: The Electrostatic Discharge Test exposes the radio to up to 25 kilovolts to make sure it can withstand the most severe static build-up while you are out on the job.
• Severe Electrical Environment Test: The Jensen Heavy Duty radio is designed to survive an alternator battery disconnection, because it is equipped with the necessary component to prevent "Load Dump" destruction.

Single DIN Mounting: This unit is designed for installation in a vehicle with an existing 1-DIN radio opening. In many cases a special installation kit will be required to mount the radio to your vehicle's dashboard. The JHD12B features an integrated trim-ring (non-removable) and pre-installed cage (removable).

2-Line Power System with Non-Volatile Memory: The Jensen Heavy Duty series head unit features a 2-Line Power System which prevents battery drain when the vehicle is turned off.

However, the JHD12B does not support song/artist/album info display. You can pair up to 5 Bluetooth source devices with the JHD12B, but only one can be used at a time for playback.
