蓝牙(Bluetooth)是一种几乎通用的短距离通信技术，从智能手机到咖啡机，无处不在。该技术的最新版本非常节能，可以传输大量数据并且几乎没有明显的延迟。因此，新车型现在内置蓝牙(Bluetooth)也就不足为奇了。
问题是，如果您的汽车没有(doesn’t )用于汽车音响(car audio)的蓝牙(Bluetooth)，您该怎么办？即使有，你如何使用它？
不要忘记(Forget)USB电缆(USB Cable)适配器
人们转向蓝牙(Bluetooth)进行汽车连接的原因之一是智能手机耳机插孔的迅速消亡(death of the smartphone headphone jack)。您的汽车或车载收音机(car or car radio)可能有辅助插孔，但您的新手机可能没有。
好消息是，您可以使用USB（或 iPhone 的 Lightning）转 3.5 毫米插孔转换器来(to 3.5mm jack converter)恢复该功能。
它们通常也不那么昂贵，但有一个重要的警告。有些手机没有内置的DAC或数模转换器，无法与(digital to analogue converter)USB 端口(USB port)配合使用。所以你需要购买一个内置DAC的适配器。这些更贵，所以做一些(DAC)谷歌搜索(Googling)来确定你的手机是否需要一个支持DAC的转换器。
与蓝牙(Bluetooth)相比，这是迄今为止更便宜、更可靠的解决方案。虽然，它不那么优雅，并且伴随着使用电缆的所有麻烦。
推荐的 USB 适配器
如果您是iPhone 用户(iPhone user)，我们建议您选择Apple 原装适配器(Apple original adapter)，它可以保证正常工作。这个便宜的加密狗唯一真正的缺点是你不能在使用它的时候给你的手机充电。
如果您有像Samsung Galaxy Note 10+这样没有DAC的手机，那么像WKWZY 适配器(WKWZY adapter)这样的适配器是一个不错的选择。它有一个内置的DAC，因此不依赖于手机的硬件来产生声音，这使它成为一个安全的选择。
蓝牙到辅助适配器
如果您的汽车没有(car doesn)蓝牙，(Bluetooth)但有辅助插孔，您仍然可以使用蓝牙耳机(Bluetooth headphone)适配器为其添加蓝牙功能。(Bluetooth functionality)这些设备旨在让您将任何耳机变成支持蓝牙(Bluetooth)的一对，但它们也可以直接连接到您的汽车。
唯一真正的缺点是，如果您需要它们持续运行的时间超过电池的使用寿命，它们需要USB 电源。(USB power)从好的方面来说，当您在旅行结束时下车时，您只需插入耳机即可上路。
推荐的蓝牙(Bluetooth)到辅助(Auxiliary)适配器
在为您的汽车寻找可插入辅助音频插孔的优质(audio jack)蓝牙(Bluetooth)接收器时，由于超级用户的评论，两款产品脱颖而出。
第一个是Mpow 接收器(Mpow receiver)。它具有最新的蓝牙 5.0(Bluetooth 5.0)技术，这意味着您将获得非常高质量的流媒体，而不会卡顿。我们也非常喜欢包含一个小的状态屏幕(status screen)，这样您就可以快速查看连接的内容以及信号的好坏。Mpow声称有 40 英尺的射程。因此，除非您驾驶旅游巴士(tour bus)，否则您可能会没事的。
下一个诱人的选择(tantalizing option)是 TaoTronics蓝牙接收器(bluetooth receiver)。该产品没有屏幕，但也可以充当蓝牙发射器(Bluetooth transmitter)。除了简单地在您的汽车中使用它之外，这使得它非常通用。
蓝牙调频发射器
如果您的收音机没有(radio doesn)辅助插孔，一切都不会丢失。您可以使用FM 蓝牙接收器(FM Bluetooth receiver)来融合新旧技术。通常这些小工具会从你的 12V打火机插座(lighter socket)上运行。
您将使用智能手机连接到设备，就像连接到任何蓝牙设备(Bluetooth device)一样。一旦该连接正常工作，只需将您的汽车收音机(car radio)调谐到设备正在广播的FM 频率。(FM frequency)您甚至可以更改广播频率(broadcast frequency)。
虽然这些 FM 发射器非常整洁，但您真的应该只将它们用作为您的汽车安装蓝牙的最后手段。音频质量充其量与模拟收音机一样好。它们还容易受到无线电台和同一频率上任何其他无线电波源的干扰。
如果您想在更旧的车辆中使用蓝牙音频并且不想花太多钱，这是最好的解决方案。但是，如果您有任何其他选择，我们建议您先尝试一下。
推荐的蓝牙 FM 发射器(Bluetooth FM Transmitters)
我们真正喜欢的第一款FM 发射器是这款(FM transmitter)IMDEN装置。它直接插入您的打火机插座(lighter socket)，并通过快速充电USB A 端口(USB A port)或 18W USB-C供电端口(Power Delivery port)提供直通式充电。令人惊讶的是，它还提供免提通话！使用它就像将您的收音机调到一个开放的频率，然后将此小工具设置为相同的频率一样简单。
需要第二个选择？Zeeporte提供基本相同的功能集，但具有不同的设计并提供 27W 的充电功率而不是 18W。这有点像两者之间的硬币翻转。(coin flip)
购买支持蓝牙的收音机
许多现代汽车都配备了工厂安装的收音机，这些收音机集成到不可拆卸的外观中。然而，在较旧的汽车中，更换整个收音机主机(radio head unit)通常很容易。如果你有幸拥有这样一辆汽车并且不(car and don)介意花(t mind)一点钱购买一台新收音机，那么获得蓝牙音频(Bluetooth audio)实际上是相当轻松的。
即使是入门级汽车(level car)收音机现在也有蓝牙(Bluetooth)功能，一旦安装，就像把你的旧垃圾带入 21 世纪。好吧，至少在听音乐和播客(music and podcasts)方面。
推荐的蓝牙收音机
如果您确实想全力以赴并更换汽车中的整个收音机，有很多选择，但最受欢迎的选择似乎是这款BOSS Audio Systems 616UAB Multimedia Car Stereo。它是一个单一的DIN 单元(DIN unit)，应该适合大多数汽车，而且价格也很低。这个现代预算主机(budget head unit)不会播放 CD 或磁带，但您几乎可以在数字方面受到影响。
如果您现金充裕，那么这款Pioneer FH-X730BS Double-Din拥有您想要的蓝牙，(Bluetooth)以及(bell and whistle)您能想象到的所有其他花里胡哨。在这两个选项之间，您一定会找到合适的。
连接到现代汽车的蓝牙(Bluetooth)
如果您有一辆内置蓝牙(Bluetooth)的新型汽车，您如何实际连接到它？好消息是，如果您曾经使用过任何(any )蓝牙设备(Bluetooth device)，则该过程基本相同：
- 请参阅您的汽车手册，了解如何启用蓝牙(Bluetooth)配对模式并按照说明进行操作。
- 打开手机的蓝牙设置并在可用(Bluetooth)蓝牙(Bluetooth)设备列表中查找您的汽车名称。点击它开始配对。
- 您汽车的信息娱乐显示屏很可能会显示密码。当电话提示时，输入该代码。
- 汽车和电话(car and phone)现在应该已配对。
- 您可能必须选择是否由汽车系统处理呼叫、媒体或两者。
这就是它的全部。有些汽车具有特殊的手机兼容性，例如Apple Carplay，但总的来说它与任何其他蓝牙连接(Bluetooth connection)没有什么不同。
How To Use Bluetooth For Car Audio In An Old Or New Car
Bluetooth is an almost universal short-range communications technology found in everything from smartphones to coffee makers. The latest version of the technology is incredibly power-efficient, can transfer significant amounts of data and has little perceptible lag. So it’s no surprise that newer models of vehicles now have Bluetooth built in.
The thing is, what can you do if your car doesn’t have Bluetooth for car audio? Even if it does, how do you even use it?
Don’t Forget About USB Cable Adapters
One of the reasons that people are turning to Bluetooth for car connections is the rapid death of the smartphone headphone jack. Your car or car radio probably has an auxiliary jack, but your new phone likely won’t.
The good news is that you can get that functionality back by using a USB (or Lightning for iPhones) to 3.5mm jack converter.
They usually aren’t that expensive either, but there is one important caveat. Some phones don’t have a DAC or digital to analogue converter built in for use with their USB port. So you’ll need to buy an adapter that has a DAC built in. These are pricier, so do some Googling to determine if your phone needs a DAC-enabled converter or not.
This is by far the cheaper, more reliable solution compared to Bluetooth. Although, it is less elegant and comes with all the hassle of working with cables.
Recommended USB Adapters
If you’re an iPhone user, we recommend simply going for the Apple original adapter, which is guaranteed to work. The only real downside to this inexpensive dongle is that you can’t charge your phone while using it.
If you have a phone like the Samsung Galaxy Note 10+, which lacks a DAC, then an adapter like the WKWZY adapter is a good choice. It has a built-in DAC and so doesn’t depend on the phone’s hardware to produce sound, which makes it a safe bet.
Bluetooth To Auxiliary Adapters
If your car doesn’t have Bluetooth, but has an auxiliary jack, you can still add Bluetooth functionality to it by using a Bluetooth headphone adapter. These devices are designed to let you turn any set of headphones into a Bluetooth-enabled pair, but they work just as well directly connected to your car instead.
The only real downside is that they require a USB power source if you need them to keep going for longer than their batteries will last. On the plus side, when you get out of your car at the end of the trip, you can simply plug in your headphones and be on your way.
Recommended Bluetooth To Auxiliary Adapters
When looking for good Bluetooth receivers for your car that plug into the auxiliary audio jack, two products stood out thanks to their super user reviews.
The first is the Mpow receiver. This has the latest Bluetooth 5.0 technology in it, which should mean that you’ll get very high quality streaming with no stutter. We also really like the inclusion of a small status screen, so you can quickly see what’s connected and how good the signal is. Mpow claims a 40-foot range. So unless you’re driving a tour bus, you’ll probably be OK.
The next tantalizing option is the TaoTronics bluetooth receiver. This product lacks a screen, but has the ability to also act as a Bluetooth transmitter. This makes it pretty versatile outside of simply using it in your car.
Bluetooth FM Transmitters
If your radio doesn’t have an auxiliary jack, all is not lost. You can use an FM Bluetooth receiver to merge the old and new technology. Usually these gadgets will run from your 12V lighter socket.
You’ll connect to the device using your smartphone the same way you’d connect to any Bluetooth device. Once that connection is working, simply tune your car radio to the FM frequency the device is broadcasting on. You may even be able to change the broadcast frequency.
While these FM transmitters are pretty neat, you really should only use them as a last resort to get bluetooth for your car. The audio quality is at best as good as analogue radio. They are also prone to interference from radio stations and any other source of radio waves on the same frequency.
This is the best solution if you want Bluetooth audio in a much older vehicle and don’t want to spend too much money. If you have any other options however, we’d suggest trying them first.
Recommended Bluetooth FM Transmitters
The first FM transmitter we really like the look of is this IMDEN unit. It slots right into your lighter socket and offers pass-through charging via quick-charge USB A port or a 18W USB-C Power Delivery port. Amazingly, it also offers hands-free calling! Using it is as simple as tuning your radio to an open frequency and then setting this gadget to the same one.
Need a second choice? The Zeeporte offers essentially the same feature set, but has a different design and offers 27W of charge instead of 18. It’s somewhat of a coin flip between the two.
Buy a Bluetooth-Enabled Radio
Many modern cars have factory-fitted radios that are integrated into a non-removable facade. In older cars however, it’s usually pretty easy to replace the entire radio head unit. If you’re lucky enough to have such a car and don’t mind spending a little money for a new radio, then getting Bluetooth audio is actually fairly painless.
Even entry level car radios have Bluetooth as a feature now and once installed it’ll be like bringing your old junker into the 21st century. Well, at least when it comes to listening to music and podcasts.
Recommended Bluetooth-enabled Radios
If you do want to go the whole hog and replace the entire radio in your car, there are plenty of choices, but the most popular choice seems to be this BOSS Audio Systems 616UAB Multimedia Car Stereo. It’s a single DIN unit that should fit most cars and comes in at a tiny price as well. This modern budget head unit won’t play CDs or cassettes, but you’re pretty much covered on the digital front.
If you’re a little more flush with cash, then this Pioneer FH-X730BS Double-Din has the Bluetooth you desire, plus every other bell and whistle you could imagine. Between these two options you’re sure to find something suitable.
Connecting To a Modern Car’s Bluetooth
If you’ve got one of those newfangled cars with Bluetooth built in, how do you actually connect to it? The good news is that, if you’ve ever used any Bluetooth device, the process is essentially identical:
- Refer to your car’s manual on how to enable Bluetooth pairing mode and follow the instructions.
- Open your phone’s Bluetooth settings and look for your car’s name in the list of available Bluetooth devices. Tap it to start pairing.
- Your car’s infotainment display will most likely show a passcode. When prompted on the phone, enter that code.
- The car and phone should now be paired.
- You may have to choose whether calls, media or both are handled by the car’s system.
That’s really all there is to it. Some cars have special phone compatibilities, such as Apple Carplay, but in general it’s no different from any other Bluetooth connection.
