How to install navigation in an Audi A3 without built-in navigation?
4 Answers
Audi A3 installation of navigation requires going to a 4S store for a re-upgrade, and adding a navigation control module. Below are the specific details about the Audi A3: 1. Exterior: The 2020 Audi A3 retains the overall design of the current model, but the body color options have been increased to six. Additionally, the S-Line model now features the S3 version's air intake grille, providing consumers with a richer selection. 2. Interior: The 2020 Audi A3's overall interior design remains unchanged, with only minor upgrades. For instance, the 35TFSI Fashion trim and above models come equipped with red RS air vents and S-series steel footrests. However, in terms of configuration, the new model has undergone certain upgrades, such as standard cruise control and electrically heated folding exterior mirrors across the entire lineup.
I'm quite qualified to answer this question, as I just helped my neighbor with his Audi A3 last week. There are basically two approaches to adding navigation: either replacing the center console screen or installing an additional module. For screen replacement, I recommend an aftermarket Android screen—a 10.25-inch one costs just over 2,000 RMB and comes preloaded with both Gaode and Baidu navigation, plus you can install apps like iQiyi. If you opt for a module, go for a CarPlay box; just plug it in to use Apple Maps, though it's less friendly to Android users. Key reminder: make sure the reverse camera wiring is connected correctly, and you'll need a diagnostic tool to clear any fault codes after installation. If the installer isn't skilled, the clips on the AC panel can easily break. It took me 4 hours to install it myself, but for beginners, it's safer to spend 300-500 RMB and hire a professional.
As a tech enthusiast who frequently tinkers with car infotainment systems, I'd recommend prioritizing the CarPlay solution. Just purchase an external module about the size of a cigarette case, plug it directly into the original car head unit interface without any wire cutting. Search 'Audi A3 CarPlay module' on Taobao for around 300 RMB, and you can project your phone navigation directly onto the factory screen - even Siri works. The downside is Huawei users would need to switch to iPhone. Upgrading to the factory navigation is also possible, but costs absurdly: requires replacing the head unit plus GPS antenna, followed by software matching - easily 7,000-8,000 RMB. Honestly, map packages become outdated in two years, making phones far more convenient. Don't fall for merchants pushing complete screen replacements - the original MIB system's audio quality is vastly superior to aftermarket screens.
It depends on your budget and needs. For a simple solution, use a phone mount + Bluetooth. For a temporary fix, go to an auto parts store and spend 150 yuan on a magnetic mount, then connect to the car's Bluetooth for navigation audio. For long-term use, three options are recommended: First, upgrade with OEM parts—order an original navigation module from a 4S store. It's expensive but integrates with the dashboard. Second, opt for an aftermarket large-screen navigation system, which offers many features under 2,000 yuan but has poor sound quality. Third, the most cost-effective option is to buy a second-hand OEM head unit from Xianyu and flash it yourself. Note that modifying wiring may void the vehicle's warranty, so it's best to go to a professional modification shop.
