320A is an Ethernet instrument cluster that does not support map projection, while the 790 supports map projection. Relevant information about automotive instrument clusters is as follows: Introduction: The instrument panel, or instrument-panel, is a rigid flat plate or structural component used to install instruments and related devices. It can be categorized by type into screen-type instrument panels, frame-type instrument panels, channel-type instrument panels, and cabinet-type instrument panels. Function: The instrument panel can be equipped with external lighting and may also include an attached control console. It comes in various forms and specifications, allowing for the installation of different instruments as needed, or the combination of various instrument panels into a single unit.

I recently researched Volkswagen's instrument clusters, and the main differences between the 320A and 790 lie in hardware specifications and software features. The 320A is typically configured in entry-level models, with a smaller screen size and more basic display content, such as conventional information like RPM and speed. The 790 belongs to the high-end version, featuring a larger screen with higher resolution, capable of displaying navigation maps and multimedia information, and also supporting theme-switching functionality. Upgrading to the 790 indeed enhances the driving experience significantly, especially during nighttime driving, where the clarity advantage is more pronounced. However, when installing the 790, compatibility must be considered—vehicle gateway protocol matching needs to be confirmed; otherwise, it may lead to fault code issues. In terms of price, the 790 is certainly more expensive, but owners who have used it find it worthwhile, as you have to look at the instrument cluster every day while driving.

How often should a new car be inspected after 6 years?

After the first six years of a new car: 1. Small vehicles: Mini and small non-operational passenger vehicles over 6 years old must be inspected once a year. Within the three-month period that includes the month of initial registration and the two preceding months, after handling all traffic violations, bring the vehicle registration certificate, compulsory traffic insurance policy, and ID card to the local inspection station for vehicle inspection. 2. Small passenger vehicles: Non-operational mini and small passenger vehicles with 7 to 9 seats enjoy a 6-year exemption from inspection, exempt from on-site inspection within 6 years, but must collect an annual inspection sticker every 2 years. After 6 years, inspect once a year; after 15 years, inspect every six months. 3. Passenger vehicles: Operational passenger vehicles must be inspected once a year within 5 years, and every 6 months after 5 years. 4. Large vehicles: Trucks and large or medium non-operational passenger vehicles must be inspected once a year within 10 years, and every 6 months after 10 years.

How Long Can a Car Sit Without Being Driven Before It Gets Damaged?

Generally speaking, leaving a car undriven for over a month can start to have an impact, though the effects are minimal at this stage. However, once it exceeds three months, the impact becomes significantly more severe. If a car isn't started for a month, some mechanical components may be affected due to insufficient lubrication from the engine oil. Beyond three months, the engine oil can deteriorate due to oxidation, and certain parts may rust or corrode. Consumables like the battery, tires, and paint will also be affected to varying degrees. If a car is left unused for an extended period, the following measures should be taken: 1. Park the car in a garage if available; otherwise, find a safe, dry, and shaded spot to park and cover it with a car cover. 2. Disconnect the battery. Only the negative terminal needs to be disconnected. 3. Clean out all items from the interior, especially avoiding leaving snacks inside. 4. Maintain sufficient tire pressure.

Where is the oil filler cap located on the BMW 3 Series?

The oil filler cap on the BMW 3 Series is located in the recess above the BMW emblem. Method for checking engine oil: After turning off the engine, let it sit for 15 minutes before checking the oil dipstick. If you frequently need to check the oil level, you can do so in the morning before starting the vehicle, as the oil level at this time is also accurate. When checking the oil dipstick, make sure all four wheels of the car are on the same level ground, meaning there should be no tilt in any direction. A simple way to determine this is to park the car, put it in neutral without engaging the handbrake—if the car remains stationary, it is basically level. Oil dipstick: The oil dipstick is a slender metal rod inserted from the top of the engine down into the oil in the oil pan. The end of the dipstick has a marked scale to measure the oil level.

What does BMW's Digital Key mean?

BMW's Digital Key is an innovative car key that allows car owners to unlock their vehicles and perform related operations via smartphones or wearable devices, significantly enhancing the convenience of car usage. Method to set up BMW Digital Key: Create a BMW ID and add the vehicle using the "BMW" app, then access the "Digital Key" menu in the application. For security reasons, the owner must sit in the car with two regular car keys on hand, press the start pairing button, follow the instructions in the app menu, and then place the iPhone on the smartphone tray with an NFC sensor. Functions of the Digital Key: Smart lock/unlock; remote vehicle control; remote air conditioning on/off; quick key sharing; door open/close without network; vehicle anti-theft monitoring; vehicle anomaly alerts; real-time vehicle status display; historical route query (can be manually disabled); honk and flash to locate the car; open/close lock/open trunk.

How much does the Xiali aluminum alloy wheel hub weigh?

Generally, the weight of a single wheel hub is: 10.5KG. The wheel hub, also known as the rim, is the cylindrical component inside the tire that supports the tire and is centrally mounted on the axle. Common automotive wheel hubs include steel wheel hubs and aluminum alloy wheel hubs. Steel wheel hubs have high strength and are commonly used in large trucks; however, they are heavy and have a single appearance, which does not align with today's low-carbon and fashionable concepts, and are gradually being replaced by aluminum alloy wheel hubs. Standard vehicle wheel hubs: Standard vehicle wheel hubs focus less on appearance, with good heat dissipation being a basic requirement. The manufacturing process typically involves painting, where the hub is first sprayed and then baked, making it cost-effective, vibrant in color, and long-lasting. Even when the vehicle is scrapped, the color of the wheel hub remains unchanged. Mass-market vehicle wheel hubs: The surface treatment process for mass-market vehicle wheel hubs. Some stylish and dynamic colored wheel hubs also use painting technology. These wheel hubs are moderately priced and come in a complete range of specifications.

How to Check a Relay?

Automotive electromagnetic relays serve three main functions: 1) switching, 2) overload protection, and 3) fault protection. The methods for testing automotive relays include: 1. Static testing: Measure the coil resistance and normally closed contact resistance; 2. Dynamic testing: Apply power to the coil and measure the normally open contact resistance. The methods for determining relay condition are as follows: 1. Open-circuit testing: Use a multimeter in resistance measurement mode to check the relay. Set the multimeter to R×100Ω range and verify continuity between pins (85) and (86), and between pins (87) and (87a). The resistance between pins (87) and (30) should be ∞. If the results differ from these specifications, the relay is faulty. 2. Power application testing: If the above checks are normal, apply 12V power between pins (85) and (86), then check for continuity between pins (87) and (30) using a multimeter. If the results don't match these specifications or if the relay heats up after power application, it indicates the relay is damaged.
