I have a Mercedes chassis with infotainment center. The RV has outside speakers. While parked and plugged into shore power, the radio shuts off after 30 minutes. I read somewhere that the stereo is on a timer. Has anyone figured out how to use the stereo for a longer time? After all, why would there be outside speakers?

Your outside speakers are not part of the chassis radio system. Look around for the sound system that operates with your TV. Normally these contain a radio and DVD player and can be connected to the outside speakers.

After you turn off your Sprinter and exit the driver door, reach back in and turn the entertainment system back on by pressing on/off button to lower right of the screen .
The outside speakers are definitely part of the Mercedes MBUX infotainment unit. It plays the radio (or bluetooth, sirius, etc) to the outside speakers when switch inside the coach is turned on (located by the step with other switches). I've used it in this manner, but only for 1/2 hour when the RV is shut off and plugged into shore power.
I also have a 2020 Qwest and noticed the same thing. There is a switch inside the door which allows either the inside or outside speakers to play and only work with the chassis head unit.
Certainly doesn't make sense, however, you're not alone!! If I find anything out, I'll let you know. Please do the same

Thank you for your reply. I recently learned that you cannot stayed plugged into shore power for any length of time without running the engine. My starting battery had discharged and would not start without jumping from the house batteries. I am going to buy a small trickle-charger to use next time. I will get a small one that will fit under the hood and plug it into the outlet inside the passenger side outside compartment, or plug it into the power post at campground. I will be curious to see if the stereo/infotainment system will stay running longer than 1/2 hour if the battery stays fully charged.??
If you look at your owners manual it tells you how to disconnect the battery while parked on in storage. The disconnect is beside your right leg below the knee.
I've noticed the exact same thing. The chassis radio is connected to both the outdoor speakers and the coach indoor (rear) speakers, but what good is that if you can't switch the system over to run from the house batteries? It makes no sense! I've asked the dealer about this and gotten nowhere at all. We carry portable speakers and use our phone and bluetooth, but it would make much more sense to use the built-in system.
If anyone has a way to get an answer from Entegra and/or a way to switch the system over to house batteries, I'd love to hear it!
