I have the Base 3.0 radio and am wondering if there is any way to keep listening to the radio after the engine is turned off without having to cycle the push button start back on?

In my Murano, I just quick tap the start button twice. No foot on the break. Engine is off and radio and accessories on. Try that.

Is there a way to extend the engine-off accessory time? I think the max on my car is ten minutes. Of course opening a door shuts everything down.

I'll try that. In a ND Miata forum someone else mentioned that. They said that is the "emergency stop procedure" in their manual.

So your saying yours stays on after the engine is turned off?

Yes, it's a fairly common feature these days. I just push the start/stop button (without touching the brake pedal) to re-establish power if I want it for a few more minutes.

Remember the good-old-days of just turning the key to "Acc"?

That's odd because mine wouldn't do that in the garage tonight but I think I already had the door open - maybe that screwed it up? Hmmm,...anyway, I'll test that out when I get to work tomorrow.

At least my other car still uses a key!;)

My car's settings menu offers three time delays, 45 seconds, 5 minutes, or 10 minutes.
I see the problem - you have the 7.0 radio. I tried to see if it would turn off this morning upon opening the car door, and the car just set of the warning chime and wouldn't let me do anything until I cycled the ignition on and then back to off. This is the only thing that is disappointing about the car.

Pushing buttons quick didn't work either.

At this point I'm going to look into rewiring the radio unit off the ACC push button sequence and add a separate switch to turn the unit on and off. It doesn't look like the unit itself does anything other play music and connect with a persons phone, so I think it's doable.

Anyway, thanks for the suggestions.

Well, I'm half way there - if I hit the Start/Stop button while the car is still in Drive, the radio will stay on. I then put the car in park and pull the hand brake. So that saves one button push and allows me to listen to the radio uninterrupted.

Unfortunately the next button push lights up all the gauges and primes the fuel rail, which is what I'm mainly trying to avoid. I blame Mazda for this stupid bit of engineering oversight.

They want you to use the CMU lol, I'm not sure where or how the base car interfaces with the ECU other than the OBDII port, as this is a function that other cars will let you adjust via the ignition, and or gauge cluster.

What's the CMU? - I'm terrible with acronyms. I'm hoping the ECU doesn't ever pay attention to whether the radio/phone unit is on, which would make wiring it up off the ignition easier. I need to find some electrical diagrams.

The CMU (Control Master Unit) is what controls the additional features that are not on the base car, from what it looks like the base radio is just that a radio, you may be able to wire it the way you were looking to. My suggestion was more along the lines of being able to program the delay via the ECU without having to rewire, as you can with other cars with an OBII tool if they don't allow for the ignition/gauge cluster programming.

Sonny,

Where did you get the diagrams? Is there a service manual available for this car?

These are from the MX-5 forums, someone has a manual for the ND. I realized I biffed the above, its Connectivity Master Unit oops. I was exploring the idea of a radio delete for the base radio, however now that I have seen the hack for Android Auto I'm more than likely going to skip the base radio.

Connectivity Master Unit - that's a new one to me.

Thanks for posting those images/instructions. I might try and pull the unit out this weekend and take a look. I may not have to though now because tonight I did the Start/Stop with the car in Drive again which left the radio playing and this time managed to get my timing of the double push just right that it skipped through the ignition sequence and went to off. I saw one yellow light blink briefly though.

Has anyone figured out a way to accomplish the radio staying on with the 9 speaker and manual trans? Can't remember the last car I owned that didn't leave the stereo on until I opened the door, so a bit disappointed by this. My morning work ritual requires finishing my coffee and hearing the end of whatever song is playing before I hit the office. Must be a way.

Just push the engine button again and it powers up the accessories. The first button push, by the way, doesn't start the fuel pump if you don't have your foot on the pedal (at least on my car). The 2nd one does. (You can hear it clearly.)

That gets the music going again, but not until Bluetooth has reconnected, streaming starts up again and usually a different song. I know this it's 1st world stuff, but it's annoying when every cheap rental car I've driven has this ability.

The problem with this is you still have to push the button again, when you are done listening, which will prime the pump. If you double click at just the right speed you can sometimes bypass the pump but always some of the dash lights start to illuminate.
