This is the way it should work. Basically, the radio is more or less verifying that the channel list it has is the correct channel list. The problem is when the updating channels message doesn't go away, which happily appears to be occurring less frequently.

This happened to me for the first time yesterday too when it flashed "updating channels" for a second and went away. I think that is more how it is supposed to work. My other cars take a little longer than a split second, but it's better than coming up and not going away.

This is normal Sat radio. The issue is it locking up at "updating channels" forever until restarted.

I've put on 15,000 kilometers and witnessed 2 lockups, both reset with the 10 second power off method. Yesterday I witnessed the first 2 second updating message. I'm thinking this Sirius issue has been resolved. Now I'll consider renewing my subscription.

The issue is not fixed. Just did it again yesterday on my 2014 GLK350. I contacted my dealer and they told me MB still has not issued any fix. Today I got my Sat renewal notice which I will not take. I will just listen to my CD's.

Fix is available late September. LI has been updated.

mikedr

Very cool!

JServidio

Is there anyway to look at the LI details?

mikedr

(bump) What's the LI # for the fix? My dealer is a bit clueless.

So, I just leased the 2015 SL400. Drove it 25 miles to my home, pulled it in the garage and when I started it up again later that evening my SIRIUS RADIO was UPDATING CHANNELS. Drove around like that for about 20 minutes. Stopped for dinner, started car a few hours later and it was fine. Took it out this morning and was working fine. Parked and shopped for an hour, started car and, again, stuck on UPDATING CHANNELS. I agree that it's not the end of the world, but it is annoying. Seems like this has been a problem for several years and wondering when this will be addressed properly or if there is a resolution. Will call my dealer tomorrow (today is Sunday) and proceed from there. Will post update here - hopefully it will be a positive one. *I'm new here, so if I posted in the wrong place, my apologies... just looking for help! Thanks!

I gave you the LI number back on post #94

tbirdvet

That only noted how to reset the "updating channels" but it does not fix the issue.

tbirdvet

This issue only started with the 2014 models (stuck on "updating channels") until vehicle restarted.

mikedr

Short answer is, reset the radio; hold down the power button of the COMAND unit until it reboots.

There supposedly now is a fix as of late September, but I haven't checked with my dealer yet. I will tell you that he had the car for multiple visits, and finally confirmed the issue.

Just bought my wife new 2015 GLA 250 2 weeks ago. "Updating Channels" started about 3-4 days after purchase. Took to local dealer, said they did a complete "reset", but of course, started happening again the next day.

So, still not fixed, issue is pervasive through many models apparently.

mikedr

Here's the irony of the situation. Since I subscribed to Sirius (no more 3-mo trial), the problem appears to have gone away.

tbirdvet

Is your radio still OK?

RSNovi

I haven't seen the problem with my radio for a few months either. I did let the subscription lapse and then reactivated.

mikedr

Mine's been working great. Since subscribing to Sirius I think the problem may have happened once, over a period of greater than a half year I think. Whereas before, it happened at least 2-3 times a week.

Software update is available as per the LI. For MY2015 vehicles with NTG4.5 GEN3 head units, this will also become a service campaign.

tbirdvet

What about 2014 vehicles?

MBtech1098

The LI addresses those vehicles. See your dealer and they will update the COMAND.

tbirdvet

Do you know what the LI number is?

MBtech1098

Post 94 has the LI number. LI numbers don't change when they are updated, only the version changes. I do not post such information like that as it is not mine to distribute. A reputable Mercedes-Benz retailer also would have no problem locating the LI when you enter the dealer and provide the service advisor with the complaint you are experiencing.

The tech then has several different ways they can associate the correct LI to the vehicle as it is all done by VIN. If you have doubts about your choice of dealers service ability, then I would suggest you address that with MBUSA CAC and the dealer management.

tbirdvet

Thanks. I thought the LI number just noted how to reset the radio which really did not fix the issue but if it is updated with the fix then I now understand.
