And I used the 0 narrow so far for on axis like a few I have seen placing the mic around the headrest.

While sitting in the car (as I am a larger mass than other things in the car and I think I might make a sonic difference), I hold the mic at my mouth position, then left outer shoulder and then right.

But an Audio Pro told me to calibrate the dash drivers, tweeters in my situation (you might have mids in the dash).... from opposite sides of the driver I'm working on to get a better reading.

I think holding the mic, let alone moving it may introduce vibes and noise and kinda add things that I likely can ignore, but rather not include in the reading.

I use the UMIK-1 and held it 90, 45 and 0 degrees. Measures the same. However, it does come with a 90 degree file to use with the NanoAVR.

I have a Dayton UMM, but not from Cross Spectrum so only the one cal file. Should I be pointing the tip of the mic in direction of the soundstage vs. Pointed up at the roof?
First-timers guide to measuring your system

You can see how you're supposed to position the mic,it's usually facing the windscreen.That's the exact reason why you got the 45 and 90 degree calibration file as microphones get directional in the higher frequencies.They are to compensate for that as in the car you're not measuring on axis.
