I returned my Max360, I have a 90D that was delivered in Sept 2016 so we should have the same windshield. Range was awful due to the windshield shielding, search the forums you will find lots of similar reports. I tried my 360 and my Passport Max in many spots, in short I would typically see the police car by the time the radar went off and off axis reporting was non existent.
I am currently driving cautiously with my old 9500ix until Radenso releases their HD+ remote detector. It has a unit that will mount up front and then connects via bluetooth to the display in the car. Radenso is getting get reviews and the idea of avoiding all of the hassle with the typical remote installs is very appealing to me.
Let me know if you find a spot on the windshield that works well for you, but be VERY VERY cautious while you're driving, don't get lulled into thinking you will have typical range.
