How to Adjust the Audio System in BMW 3 Series?

In the BMW 3 Series, the volume can be adjusted either on the air conditioning panel or the steering wheel. To adjust the treble, bass, and tone, select the tone option in the settings or choose the tone adjustment in the external devices. Here are some maintenance tips for the BMW 3 Series audio system: 1. The main unit is significantly affected by weather, especially the circuit board and plastic components. The parameters of the electronic components on the circuit board vary with temperature changes. Therefore, if the car's interior temperature is high, it is advisable not to turn the audio volume too high, as this can affect both the sound quality and the lifespan of the audio system. 2. The mechanical part consists of metal and plastic components combined with a circuit board. Note that external high-power amplifiers are more sensitive to temperature changes and require large-capacity heat dissipation. Hence, during summer, ensure that the external amplifier is well-ventilated when using the audio system.

Can a plug-in hybrid run without charging all the time?

Plug-in hybrid cannot run without charging all the time. Plug-in hybrid electric vehicle (PHEV) is a type of vehicle between an electric vehicle and a fuel vehicle, equipped with both the engine, transmission, drive system, fuel line, and fuel tank of a traditional fuel vehicle, as well as the battery, motor, and control circuit of an electric vehicle. The battery capacity can also support driving in pure electric mode for a certain distance and provides a charging interface. Plug-in hybrid vehicles will not run out of power while driving. If there are charging piles nearby, they can be driven as an electric vehicle. When driving a plug-in hybrid vehicle, it can operate in pure electric mode or hybrid mode. In the battery hold mode, the vehicle is also in hybrid mode, similar to a regular hybrid vehicle.

What is the difference between used cars and new cars?

The differences between used cars and new cars are as follows: 1. Different vehicle conditions: After a new car comes off the production line, its condition is at its best, with all parts being brand new. For users, this provides peace of mind, and the cost of replacing any issues during the warranty period is relatively low. Used cars have been used by at least one previous owner, and the wear and tear on the vehicle's parts vary depending on the previous owner's usage. Most used cars are sold without warranty coverage, and many parts are nearing their replacement period. Whether it's regular maintenance or repairs for issues, the costs are generally higher than for new cars. 2. Different initial investment costs: The cost of a new car includes the purchase price + purchase tax + insurance fees + other miscellaneous expenses, while a used car only involves the car price + service fee. 3. Different psychological perceptions: Traditional Chinese psychology favors buying new over old, so the psychological acceptance of new cars is relatively higher than that of used cars.
