I added the Nissan OEM Sirius radio to the existing wire harness of my '05 Murano and while everything works well, the steering wheel only controls the volume.

I can't switch sources or tune the sat radio with the wheel. When I try to cycle through the inputs it runs through everything except the sat radio and when I try to use the tune it switches to FM and tunes that.

Is that normal?

Thanks

That's not normal. Your radio is not recognising the sat receiver at all.

Turn off the ignition, and unplug the receiver and leave it unplugged for about a minute. Then plug it in and turn on the ignition.

When the ignition is turned on (radio on or off) the radio will look for attached devices and communicate with the receiver.

If this is not working, then it's possible something is faulty, the receiver, the harness or the radio.

You may need to check the other end of the harness to ensure it is plugged in as well.

The volume control on the steering wheel only controls the radio's volume and does not send commands to the sat receiver.

You should be able to change presets on FM as well, to confirm the steering wheel controls are functioning correctly.

It's highly unlikely that your steering wheel controls are faulty.

To clarify the problem, if I use the controls on the radio everything controls the sat radio and it works as it's supposed to and the controls on the wheel step through the radio presets.

It's just when I try to use tune and the input select on the wheel that I can't control the sat tuner.

Thanks

OK, that's strange...

If the steering wheel controls all work for the radio, then the electrical path there, is fine.

If the radio controls work for SAT, then the electrical path there, is also fine.

What you describe is a software issue, since all the hardware appears to be working correctly.

I would be tempted to disconnect the power for everything, to reset it to defaults, and try again. If it still has the problem, then ask Nissan why.

With the ignition OFF, open the hood, pull out #38 for a few minutes, to reset everything. You know it's been successful when you put it back in, turn on the ignition and all your presets are wiped out.

Hmmmm, That is indeed strange....I too just last week added Sirius to my 05 MO and everything works like it should... I can use the steering controls to switch channels/inputs etc..the only thing I did notice is that when I initially installed the system and tired the sterring controls it would automatically swith me back to the FM presets, that was untill I programmed a few sat channels now everything as I said works as it should...I would try what Jaak suggested and unplug the tuner to restore the "defaults" and see what happens....

As a side note, it took me a while before I realised this, but if you press and hold the steering wheel selector for the presets, it will jump to the next group of channels.

Neat idea, but since you can't select channels from the steering wheel kind of useless.

It's more practical with CD's and how it makes it jump to the next disc.

Getting back to the problem, if the fuse doesn't clear it, then you need to swap a component, like the sat receiver, or the radio to determine where the glitch is. Hmmm... wait. Let me think this out.

If you can change channels on the radio, then the sat receiver is working correctly, and it's a problem with your radio. The steering wheel controls are interpreted by the radio and then it sends the command to the sat receiver to go to whatever the next preset is. If it's a sat preset. If it's a radio preset, it will take it to FM.

Go to a different group of presets. e.g. if you're on presets A go to B and program them all with sat channels. Then try the steering wheel controls again.

I'm not sure there is a problem here... can you be more specific about exactly what you are doing and what happens?

Be sure to program some presets with SAT stations otherwise your channel selector will not select/tune a SAT station. Not trying to say that you don't know what you are doing but I can't find a good answer from what I've read thus far.

Did the reset and everything popped in and now all functions work.

Thanks to all who replied with help.

Excellent. Scrambled code got wiped clean by the loss of power. Definately in the radio, not the Sat receiver.

This is where I get to pretend to be a Service Advisor. "Wow, I never heard of that happening before!"

Actually true this time!
