Radio does not work except for satellite radio

ANSWER : First thing I notice is you say the 120 amp fuse was blown. That requires a substantial electrical short to blow. If you disconnect the positive side battery cable and touched any metal part of the car – even for an instant – you may have created that short. Whenever disconnecting the battery, always disconnect the negative cable first. With that large of an electrical short, it is possible that the internal power amplifier of the head unit may have shorted. With any large electrical short, the power spike can easily effect any electrical component in the vehicle. Some are more sensitive than others and will not withstand even a momentary short. It is also possible there is a software issue with the head unit. If you want to retain the original unit, then a trip to your local Toyota dealership for a diagnosis is the best thing to do. Another option is to try a reputable stereo repair and installation shop to explore options of repairing or replacing the existing unit.

ANSWER : Sounds like the radio head unit is faulty. There are no serviceable parts, so replacement is the only option. You may want to enlist the help of a mechanic, such as one from YourMechanic, to access the radio and pull it out to get the part number in order to get the proper replacement.

ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

ANSWER : Hi Kritesh. It sounds like the stereo amplifier in your vehicle has failed internally, lost power, lost ground, or lost signal from the radio. Perform a quick check of the radio functions; change stations, adjust volume, etc… If all of these are showing proper changes on screen, then the problem definitely lies in the amplifier area. Using an electrical wiring diagram, locate the power source and ground for the amplifier and check with a digital volt ohm meter; repair as necessary. Based on my experience with Toyota & Lexus, I’ve found that the amplifier fails much more often than the radio. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. If available in your arear, Your Mechanic has several available technicians that can assist you with a radio has no sound inspection.

ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : It sounds like the radio unit in your vehicle may have partially failed to where the controls no longer work. I would recommend having your radio inspected by a qualified professional. This inspection may involve the removal of the radio and some sort of bench testing with a high tech scan tool or machine of some kind that is used specifically for the testing of automotive radio equipment. This electrical inspection may also include using a digital multimeter to test certain wires that connect to your radio that may control the use of the buttons on the face of the radio. If the inspection shows that your radio controls have shorted out, replace the radio if necessary to regain this function in your vehicle.

ANSWER : This is likely either a dead battery or a battery connection problem. Try checking the battery ground (black cable opposite end of the battery connection) to be sure is properly connected to the chassis of the car. An intermittent ground or simply a weak battery can cause the dimming of the lights and loss of power as you describe. If you need guidance by an expert, a certified technician from YourMechanic can come to your car’s location to diagnose the loss of power and let you know what should be repaired.

ANSWER : If you have a control knob on the console, you most likely have command. The most accurate way to determine if you have command is to call the dealership and give them your VIN. They can decode the vin and tell you what options your vehicle has. They will also be able to tell you if a new radio and NAV unit will need to be programmed for use in your particular vehicle. If you want other options, besides the factory unit, Crutchfield sells radios and installation kits for your vehicle. A local car audio shop can also provide you with different radio options and can install any radio you purchase. If you’d like a second opinion from a certified mechanic in person, consider YourMechanic, to diagnose the issue with your radio and suggest the best fix from there.
