Hello Metris fam! Just curious has anyone else reached their wits end with getting a resolution for the Metris Audio 30 not consistently connecting with CarPlay? I've been told that it is a known issue with MBUSA but that they have no resolution at this point. With the Metris soon to be discontinued in the US, my concern is that they would not be pressed to find a resolution with it no longer an issue for North America.

Are there enough bummed Metris owners who might be willing to get together to try and pressure MBUSA to find a resolution for all? Maybe pressing their legal team to do something? As the disconnecting CarPlay can ultimate lead to a liability if someone is using maps and gets disconnected and are unable to reconnect and become distracted? I know it's a reach, but I'm so bummed that CarPlay doesn't work :(

There are a couple of threads here on this issue - take a look by searching "apple CarPlay". One fix is a secondary bluetooth device that makes the connection and overrides the defective bluetooth in the Audio 30/40 head unit. We have this one but there are many others: https://www.amazon.com/gp/product/B0B4CBKNTT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
It has worked well so far - be sure to have it plugged in before you start the vehicle or it will have trouble connecting to your phone.

Thank you! Yes I know there are a number of threads but I feel that the fix should be addressed by Mercedes. It’s part of what they advertise on the vehicle, and the fact that it doesn’t work. I feel that any alternatives should be funded by them.

I wouldn't let 50 bucks stand between you and a solution.

Agreed! Particularly since, even if one were to "win" and get MB to solve the problem (not likely given how long they have had to fix it), one will not have had the utility of the CarPlay features for whatever period of time it takes to have the issue resolved by a big auto company that has many such issues on their docket. It does not reflect well on MB, but given that there is a reasonably cheap solution, albeit without MB participation, it behooves one to take it and run with it! That's what we have done.

For about 250 you can easily augment your system with a 9" screen with wireless carplay and android auto.

A buddy got one of those Android units, but for him reliability has been sketchy. To the point where he regrets it. I’m sure this is not the case for everybody, but unresponsive after-sales support is a factor when stuff goes wrong.

I was close to pulling the trigger on a Teyes or Joying, but ended up going with that Pioneer and Crutchfield for that very reason. It’s nowhere near as cool and fancy as the Android head units, but it is solid enough.

I have a 22 model Metris with the sound 30 and use a Apple 13Pro which crashes the system after 5 min. Interestingly my wifes iphone 11 and my co workers 13 do not crash it. I used my coworkers on it one day for almost 2 hrs with no issue. If you look at the apple forums it is an issue with several manufacturers on the 13, so not sure how to properly troubleshoot.

I have a Kenwood 10" and love it. Not free, but worth it. There are a couple threads on that unit. A volume knob is key.

I've had dozens of cheap Android units on other cars. I'm done with Joying. It's Atoto or Teyes really. Putting a Atoto s8 ultra plus in my wife's car this weekend with the panoramic backup camera. It's like a Birdseye 360 camera using just one camera.

The add on wireless boxes are cheap. You can get premium boxes that add things like a Sim card slot for 4g and more memory and cpu.

That carpuride is ideal for rental car trips. Nothing to connect.

Does this dongle you have correct the issue where it continuously disconnects CarPlay while driving? Mine will connect but frequently disconnect and I’ll have to unplug and replug back in. Does this solve that issue?

The model we bought works - just plug it in before you start the vehicle. If you look for the other threads on this on this forum (which should appear as "recommended reading" below this thread) you will find other owners that have used a number of different such devices with success. Pounce is correct as many of the devices are available on Amazon and have free shipping and returns (provided you are a Prime member).

Was the firmware updated by the dealership?
I seem to recall there had been an update that resolved things.

I debated replacing the head unit, but settled on an aftermarket standalone unit, hovering besides the steering wheel. Quite convenient and leaves everything factory intact, and I don't have an extra head unit sitting around that I don't know what to do with.

The first version of it - corded - was glitchy / troublesome getting connected and why I never really mentioned or reviewed it here. Their customer service replaced it with a newer wireless version and it has been 99% glitch free.
I still should do a post about it ... but I have a few too many irons in the fire, taking up mental energy and digital time.

If I need it for navigation and/or streaming audio, I click Media a couple times to get the line out - line in from the unit.
Answering the phone I do via the car buttons.
Very happy with the position and convenience.

For the SUV with wired CarPlay - pretty much glitch free; I did get a cordless dongle, after seeing the convenience and lag free experience on the van.

I'd rather try that route and having it solved, vs it not working and waiting on MB ...

Thank you! They did do a factory update and it didn’t solve the issue. I ordered a wireless dongle to try and see if it will solve the issue.
