Land Rover Discovery 4 Electrical Problems with Infotainment System

A marvelous contribution to the mid-size luxury SUV was introduced to the world in the late 80s with the release of the Land Rover Discovery. Also an off road vehicle, the 4th generation of this respected car was released in 2009 with thicker anti-roll bars and more powerful breaks to make the road-less-traveled experience even more rewarding. A common issue experienced by LR4 owners is electrical problems with the infotainment system.

The infotainment system is one of the central user interfaces the Discovery possesses. Through the system, the sound system, climate controls, weather, and car performance can be monitored. When it fails, you can expect difficulties occurring within all of these areas and beyond. Owners report that the speakers refuse to work, and the phone controls on the steering wheel do nothing as well. There are reports of being able to jolt everything back to life by simply restarting the car, but this is obviously not the most sustainable fix, especially if the problem returns.

The problem may be an electrical malfunction somewhere within the dashboard, or it could be a blown fuse. However, the chances are good that if either of these areas were to blame there would be manifestations beyond the infotainment system itself. There has been TSB (Technical Service Bulletin) issued regarding the infotainment system, and this would indicate that the problem likely lies directly within the system itself rather than with some other agent.

Taking your LR4 to a dealer for a diagnostic will be ludicrously expensive. Instead, consider stopping in at an independent import service center where highly experienced professional mechanics can look over your Discovery 4 and bring your infotainment system back up to snuff in no time at all, and at only a fraction of the cost demanded by a dealership.

Search for a local, independent Land Rover repair shop with Land Rover mechanics that have dealer-level expertise at a fraction of the expense.
