I can thoroughly recommend this. I used the microphone from my home Yamaha 7.1 amp and what a huge difference. I have struggled to get the best out of this unit and now it sounds incredible.

I also jailbreaked my iphone and can now mirror TomTom in app mode (sound & visual) thanks to the advice on here.

+1 I thought I had things sounding pretty great until I got a big improvement doing AutoEQ with the mic from my home Sony.

do you need a special mic? I tried with a regular mic and for some reason when I hit start it comes back with "Error. Please check MIC."

My mic is for setting up a surround amp at home, wasn't a Pioneer or anything special. Just make sure you push it in all the way, mine didn't do anything until it went the last couple of millimetres.

I went ahead and ordered the pioneer mic. (But it's on Back-order....)

Just bought a mic on eBay. Had the same error message with my home theater mic.

I have the mic that came with my Sony home theater receiver, I guess the mic gets placed in the center of the cabin for best results

According to the manual you should put it on the driver's head rest.

I stuck mine to the headrest and left it to it, takes 5 minutes. Just replaced the Porsche front speakers with Alpines so I need to run it again.

Just did mine. Huge improvement in SQ. Wish I had noticed it sooner.

Can you give a link to the mic you bought off Ebay?

Mine had a Buy It Now for $15. Only one I see now for cheap.

Why is this mic so hard to find anywhere to buy??

Also, i cant seem to get auto EQ to turn on at all. I plugged in my Denon surround mic figuring it may work. But i can't even turn on auto eq to test it out.

Any ideas? Thanks

It is most likely the mic itself. I have an Arcam mic that I plugged in and it didn't work. The Pioneer mic was detected immediately, ran through the test and all was good.

Looks like a new batch is coming through in a few weeks.

I have a Sony mic that came with my home theater receiver and it worked perfectly

I have to say that I was pretty dissappointed with the Auto EQ curves in my truck. They sounded really cruddy compared to what I had set the EQ to by ear .. :/

Having trouble with this. I have both a mic from my Onkyo home theatre and I just got the pioneer one off amazon for $15. When i try to use them, i get the same error message from an earlier poster "Error, Please check MIC". Tried adjusting them in the socket but no dice. I plugged an audio cable in to see if the cable was connected, music came through just fine. My deck was professionally installed and i have the brake sensor modded by them and the PAC infrared remote add-on. I just swapped my amp and put in a sub and want to get this thing tweaked a bit.

Where did you plug it into. I accidentally plugged it into the W/R slot on the back of the unit. Brought it back to installer and realized it had to be hooked up to auxiliary input wire.

I had the same problem on the 940BT using the mic from my Onkyo receiver. I discovered that the noise I made closing the door before the test began would give me the error. When I quietly closed the door it worked without a hitch. Don't know if this will help, but it seemed to work for me.

I'm not sure, i had it installed by an authorized reseller shop. I pulled off some of the dash to try to get a look at it, but didnt want to completly disassemble it. Laziness and it was 112 out. I think it is the aux wiring though since i can play audio through the same wire just fine. I put in a support request to pioneer and they just gave me the support line number and said best to call it in. So i will give that a shot.

With both my onkyo and the pioneer model, i cant get it to start the test. It immediately throws that error when you hit Start.

Thanks for the suggestions, I'll update if i can get a resolution... or not i suppose.

Did you make sure that you press the audio off option to turn all audio off. It doesn't work for me unless I do that. Also, I got better quality by putting the mic in between the 2 driver seats, than I did putting it in the driver's side headrest. Then again, I was using the pioneer mic that I got off amazon.

I hope I can does this on my 920 once pioneer releases an update for it.

where do u plug the mic?

did you read the manual? it says in there. Answer for lazy folks: in the aux input (i.e., ipod/iphone cable jack)
