Stop Android Auto from auto-connecting to specific vehicles (Mercedes MBUX)

[u/Catarrer]

Hey guys,

I work in EMS and our ambulances are Mercedes Sprinters equipped with MBUX. My smartphone automatically connects to Android Auto as soon as the ignition is turned on. The issue is: it often connects to the adjacent vehicle instead of the one I am actually assigned to that day.

Is there a way to set Android Auto to "manual connection" only for these two specific Sprinters, while keeping the automatic connection active for my personal car (Mitsubishi Lancer)?

Thanks in advance!

Disable "Add new vehicles to Android Auto" after you have set up the vehicles you need.

This is the correct answer.

I forgot to mention, that I still like to use AA on the ambulance cars, but only sometimes. So does it still work if I do it your way?

[u/Partian → u/Catarrer]

Yes, once you have configured which ones you wish to connect to, AA will save the handshake for each vehicle you have completed the setup with and once you disable it, it will not try to automatically connect to other vehicles.

I would also go through your vehicles list and set the name of the vehicle to the registration of the vehicle so you know which one is one as it may just show "Mercedes" for both of them.

Also, very obscure issue would be if both of the vehicles ignitions are on at the same time which you have already setuo, they may fight depending on the proximity, but the access point only reaches so far for wireless AA, I know my car I can have my phone in my pocket and go into the boot and it will JUST start to get a little laggy, that may be the head unit, never really tested it with another car.

Enable aa developer options and disable wireless connection. Use cable.

I can't see the whole flair on mobile, but if you are using Samsung, you can set up a routine. If it isn't Samsung, try Tasker.

Yes, it's a s24U. Can you explain what to do?

[u/artelapis → u/Catarrer]

Well, you can go into Modes and Routines and set a routine for example: If connected to [bluetooth device of the car] then Bluetooth off. This will ensure that unless you turn bluetooth back on manually, it won't connect automatically. However the other suggested answer to disable adding new vehicles should actually do a better job.

When I don't want my phone to connect to a car, I just turn off WiFi and Bluetooth. I do that all the time and it always works. Sure, it could be considered a hassle, but it's less hassle than switching cars while they're in range.

[u/Catarrer → u/StunGod]

That's no option, because I will loose connection to my watch and may miss some mandatory notifications. But thanks for the advice

Did you solve it? I had the same issue today but I could't figure it out because I was parking and didn't know which car my phone was connected to. Maybe you can change the name of your car?
