大家好。我向丰田经销商询问了无线电代码和蓝牙代码。
经销商说我不需要蓝牙代码。他们对无线电代码的说法（例如，如果我必须更换或断开电池连接）现在是他们使用插入卷烟打火机的设备的日子，该设备使汽车保持“活着”并保持代码，直到重新连接电池为止。因此，只需获得其中之一即可。
我的反参数是，如果电池刚刚死亡并且我需要输入代码以重置/重新激活所有内容，会发生什么？ What then?
Is what the dealer says legit?
It was for a 2018 Rav4.
I don't want to end up in a situation where if the battery just dies, I have to go to a dealer and pay $$$ to have everything reactivated.

Ask them again nicely to access their database for the code. They may charge, they may not

This seems a bit too new for needing a radio code.

I don't think they use codes any more, I had to remove mine for repair once and it just booted back up once reinstalled.

O.P.

What model/year do you have?

Radio codes are a thing from the过去。
自1990年代以来还没有看到“无线电代码”设置。
从汽车收音机很昂贵且易于窃取的时期。
如今，收音机已经很好地整合到了仪表板中，并且很难窃取。

无需代码 - 不需要代码。

If you car manual says you need a radio code to reset the radio...Call A Toyota Dealer...they can access the code held for your vehicle...you may need to confirm you are now the owner..
Yes I have done这个...
o.p.

同意上述。 检查您的手册，如果没有提及在更换电池后输入代码的过程，那么几乎可以肯定不需要一个。
谢谢。 I wanted to make sure I had a code (if needed) before taking ownership of the vehicle so it would be Toyota's issue to get it to me (without cost).
But from these responses, seems like there shouldn't be one, which would be good.

这只是一个小电池，当它们交换主电池时，它将“反馈”“反馈”。 Not so much for radio codes, but station memories, and user settings such as seats and mirrors that some cars have.

Radio codes as late as 2010...of course nobody steals radios...but if you need a code..you need a code...

是的，是的，是的，确切地说，不要以为无线电问题。
但是，现代汽车有自己的问题。有时需要校准一些东西。不知道现代丰田需要什么。 I haven't disconnected my battery yet lol....

Most Car manuals (especially something as recent as 2018) are online these days, so go hunting there for the stereo & bluetooth specs.
If you find any codes in the paperwork, write them in the manual & store in the glovebox.

Agreed with others you不再需要无线电代码。当头部单元是单din或双din类型时，更多的东西。
更换电池时，最多可以消除负面，然后首先阳性和重新连接阳性，然后是负数。 Wifes 2020 Kia和我的2021标致（也从EFB到AGM电池电量）上的电池是否也没有问题。
o.p.
谢谢大家的反馈。欣赏它！

以及ECU保留其学习的代码。
某些汽车一旦丢失了。
旧的mitsu玛格纳斯（Old Mitsu）用来拒绝电池后拒绝拒绝电池后拒绝。如果您没有正确进行闲置训练，则引擎将在一个拐角处切开，而您将没有动力转向，就在您需要的地方。
闲置训练可能需要10分钟以上的时间，而汽车静止，您的脚悬停在节流器上，以使发动机在正常的闲置速度上大致延伸。它。
后来的Outlander（2016）也没有。似乎记住了那些参数。
均未需要的无线电代码，iirc。
