I have a BMW X5 3.0i 2006 with the business CD radio.
I had it in the shop for some minor work and when I got it back the radio behaved differently. (I asked the shop to see if they did something but they said they didn’t)
When I use the keyless entry to open the door(s) the radio turns on automatically. It did not do this before. This did not bother me too much until I tried to change the station. The station buttons on the radio do not work, only the volume knob and the button on the CD player works. However I am able to control the radio from the steering wheel so it looks like the radio actually works.
I’m hoping it is just some setting that someone came across. I would think there was something with the radio but the keyless entry makes me think it’s some setting.
Any help would be appreciated.
