This time, my subscription still has 5 months on it.While it was doing this, I was still able to listen to the channel I had it originally tuned to.I was still able to listen to channel it was stuck on , and I tried powering off the COMAND, switching to CD player, radio, etc.Everything else works fine except for the Sat, which just continues to show "Acquiring Signal" and play my one stuck channel. I tried sending a signal refresh per Sirus XM's instructions, but that didn't seem to change anything.
I DID hear the preview channel and it's phone number.
Maybe 10% of the time, when I start the vehicle receive "updating channels." Current channel comes thru loud and clear. I don't blame your dealer as a replacement would result in the same problem. It happens on one of my older MB's all the time, never on the newer ones. I'm afraid since it is not consistent the dealer will not find and repair under warranty. But switching out the control unit didn't do the trick. I had thought that perhaps it was a bad wiring harness, but if you're having the problem, too, then that's unlikely (my thinking is that the wiring harness got nicked in installation). Dealer was able to reproduce the problem, and their diagnostics were showing that the signal was coming into the control unit, but that the control unit was saying it wasn't getting a signal. I was going to see if the antenna and wires were secure before taking back to dealer.
But otherwise I'm locked out -- can't change presets or do anything else with satellite radio. I dunno -- if Mercedes is the only vehicle manufacturer that seems to have this problem with Sirius, that strikes me as a Mercedes problem. I'll let you know what happens once the antenna has been switched out. But switching out the control unit didn't do the trick. I had thought that perhaps it was a bad wiring harness, but if you're having the problem, too, then that's unlikely (my thinking is that the wiring harness got nicked in installation). I have owned my 2014 GLK for around 12 hours and on the second drive the SAT came up "Updating Channels" and never completed. Frankly, what I'm wondering is that perhaps this is ultimately a software issue. They replaced the antenna, and the problem was still present.
But, again, silly me for thinking that satellite radio that works on all other makes and manufactures of cars would also work on a vaunted Mercedes. I'll let you know what happens once the antenna has been switched out. I wasn't able to listen to the Sirius on my drive in this morning. Frankly, what I'm wondering is that perhaps this is ultimately a software issue. So this is definitely an endemic issue to new 2014s. I don't know where the satellite module is, unfortunately. They were able to do a lot of troubleshooting, however.
Standard dealer proedure would be to reboot the system - then put it outside to see if it accepts SIRIUS update - if it does not then the COMAND unit would be ordered in to replace your unit. I have owned probably 6 other cars with Sirius/XM and have had channel updates on rare occasion, but they would only take a few minutes to complete. So this is definitely an endemic issue to new 2014s. I don't know where the satellite module is, unfortunately. Furthermore, they contacted the national Mercedes people -- this problem is widespread all over the country.
