Installed my 9500ix on my MYP22 using:
Radar Mount Mirror Mount Bracket for Escort Radar Detectors - Escort 9500ix, 8500x50, Solo S3, Redline (3001001)
https://www.amazon.com/dp/B0063N7OZ2/
And:
Escort Direct Wire Power Cord for Radar and Laser Detectors
https://www.amazon.com/dp/B0003NN83U/
Connected/tapped in to power at the passenger footwell per instructions on this thread.
RD powers on upon touching the break pedal on entry and off upon exit.
Did have to do a small trim to the mirror plastic trim.
Very happy with the outcome.
Thanks to all for sharing info, following multiple videos and post made it easy!
