Hello,
I just recently purchased a 2010 E350. I did a lot of research and found out how to enable bluetooth audio from the engineering menu. It works, however, it must be connected by using the iphone to search for the Comand. However, whenever I turn the car off, I need to reauthorize this again.
I see many people with this issue.
Has anyone actually solved it? I called my local dealer, and they seem clueless about a firmware update. Is there a way to update the firmware myself?
Does anyone have any solutions?

I have a 2010 e350 coupe, I could not use bluetooth audio streaming.
Phone works just fine, but in the menu there is not even an option for bluetooth audio streaming.

Dealer says my car does not have a comand with bluetooth audio capability?
and they say it is too expensive to get a bluetooth streaming version?

Btw, in the engineering menu I could not turn it on neither.

Do you have any suggestions for me and how expensive the system update?

I have the exact same problem, does any one found a solution to this problem?

Are you still under warranty from mercedes ?

OnlyGerman

Is it there, i saw it before just forgot what selection it is.. Once you find it turn it on.. then tell your dealer bluetooth audio keeps needing authorization on start.. They should update it if your under warranty for it to show Bluetooth Audio under "Audio".

Thank you very much, I will take it to the dealer for update

I just purchased a used (CPO) 2010 E550. I enabled BT streaming and the air-conditioning display in the engineering menu.

I can't get streaming to connect with my iPhone 5, but I don't know who's fault that is. In the phone menu, for connecting a new phone, I don't have an external auth option - only auth. (BT phoning works fine)

I've taken some pictures of any screen that seemed to show a S/W version, though none of them show anything similar to the version #s in a previous post above: SW Version: 0029024000 to 0009026706-001

Before I go thru the trouble of trying to get a software upgrade, does anyone know whether I could benefit from an upgrade?

What's with these apple products? Got an ipad mini and same thing with the wifi. Cuts out, have to reauthorize on my home network everytime.

Arrie

Have you tried EXTERNAL AUTHORIZATION in the car's menu?

johnlk25

Could you give instructions on how you get into the engineering menu and how exactly to enable the air-conditioning display function?

Thanks!

OliverU

Thanks Arrie, I found that option - I wasn't expecting it off "Update". Ok, so now BT streaming with my iPhone5 is working!

I'm still wondering whether I'm running the current version of SW. The POI Map option is disabled - this tells me I'm running older SW. BT streaming is working, though not showing song/artist info - I thought an upgrade was needed for the 2010 E for BT streaming to work?

OliverU

Instructions to open the menu are quoted in post #21 in this thread. From there, the AC option is here:
7. HW Setting
7.7 HU Parameter
(28) Aircondition Status

Further down is the setting to turn on the display of Hybrid stats. I turned a couple on, but haven't driven the car yet. One of them made a historic graphical consumption chart appear, of the past 15 minutes or so.

Arrie

I had 2011 E350 and it did have audio streaming but it did not work correctly. One of the problems was that I had to authorize it every time when I started the car. After updated SW it did it automatically.

I now drive a 2010 E550 and have the updated SW and it works flawlessly.

johnlk25

Ok, I'm going to try this in a little while but I'm a bit nervous.......is there anyway that I could possible screw anything up? I dont want to end up completely disabling my Command system or anything.

OnlyGerman

I was nervous at first as well but just follow the instructions and you will be fine, don't worry..

johnlk25

It worked! But it only shows the temperature displayed in the Command unit, not the fan setting and the mode that its in though. But I'm happy with it just showing the temperature on the Command display.

OliverU

Having tried it now, I am being forced to reauthorize too. Okay, that proves I can benefit from a software update - thanks!

Arrie

After the software update you may run in the problem of lost audio that happens randomly. In case this happens your dealer needs to revert the SDAR software back to make the system stable. After this you will still have BT streaming and all.

OliverU

OK, I'll watch for that. Bt audio has already cut out for a second at a time, twice. Let's see what happens after the update.

OliverU

BT streaming:
I no longer need to re-authorize for BT streaming.
BT streaming shows the song/album/artist names.

Nav:
While looking at a POI, the map option is enabled.

Traffic:
I was hoping, but wasn't expecting traffic to start working after the SW upgrade. After re-sending the signal from the Sirius site (I had tried this several times before the upgrade) - I now see traffic.

Arrie

Good it all works! Let's hope you don't run to those random system mute issues. If you do then go back and ask them to revert the SDAR SW.

If i dont have navi, can i update using software DVD to get this (BT stream) working.

OliverU

I'm guessing you have Audio 20 or 50. I don't know what BT functionality those have. I'd start a new thread with that question.

kpotdar

Hi All,
I followed the instructions here and activated the BT Audio. Then did External Authorization to connect My Iphone 5. My iphone5 was connected previously as a phone, but when I connected it as a BT Audio device, the phone over BT stopped working.

Any Ideas would help?

Thanks

Newbie

Do you still have the receipt from when the dealer did the update, my dealer is asking for some sort of reference.... the tech's here in CT are clueless
