Sony AX6000 - Factory mic audio quality? iDatalink MIC1 vs aftermarket mic?

TL;DR 2014 Prius Three factory mic good enough for iDatalink MIC1? Or just save my money & get external mic instead for Sony AX6000?

Hi! My 2014 Prius Three's radio recently got upgraded to the Sony XAV-AX6000 and Maestro RR & I am enjoying the new features. Didn't realize though that when on CarPlay the mic input comes from the head unit and I did not plug in an external microphone...so other people can't hear me. ☹️ Also, I didn't get the mic that came with the head unit as I bought it off someone on FB Marketplace.

I was debating on getting the iDatalink ADS-MIC1 to keep my factory mic or just get a 3.5mm external mic replacement. But is the sound quality of the factory mic even worth the $80 MIC1?

For those who used the MIC1 what's your experience like? If you prefer an external mic replacement, what are some of your recommendations?

Thank you!
