So, the stereo harness adapter came in from Bergvill.
I had the CDR-210 factory unit,
you need this adapter to connect
Continental head unit TR7412UB-OR.
Bluetooth and radio work great, stereo is great, reception is great, no complaints.
How the Bergvill harness connects to the Conti stereo.

I did have to shave off a little of the inside frame so the stereo retention sleeve would fit.
Don't forget to bend the 4 inside tabs and two bottom tabs on the retention sleeve to prevent it from sliding back out.
All buttoned up and fully functional.
