We have a 2007 R350. Seems like the radio display is locked

Customer Question

Hi- we have a 2007 R350. Seems like the radio display is locked to just the Mercedes Icon. The radio station is playing but the steering wheel controls are not working to control any radio functions.Any ideas?
JA: Many things can cause steering issues. Some simple, some complicated. Fortunately, the mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: It's nothing to do with steering, just the radio function. The audio display is not changing from the initial Mercedes display on the screen.
JA: Are you hoping to fix this yourself?
Customer: I guess it depends. If it's a simple fix, probably, if complicated probably not. This is my wife's car so I don't drive it often. I'm hoping something can be easily reset.
JA: Is there anything else the Mercedes Mechanic should be aware of about your Mercedes?
Customer: No
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Mercedes Mechanic about your situation and then connect you two.

Hello. There are only two options we can do. Pull the fuse to the radio to reset it or have the software updated at the dealer. I'll get you the fuse location in a moment. Lou P
Expert:  Lou P. master tech replied 1 year ago.
It is fuse 25 located in the rear fuse box next to the spare tire.

no problem, let me know if it works, this was a common issue that would happen and require a software update but with a car this old it should have shown itself years ago so the radio may have just glitched. so let me know if it works, there is not much more we can do but i would still like to know :)
