Having driven a minivan for the past 12 years, I was not overly concerned with my lead foot, feeling like the police would pity me before they would ticket me 
But I think that things might change with my grand touring, so I purchased the Radenso pro m, which would be my first radar detector in 25+ years. If possible I would like to hardwire it also. I feel like I read somewhere that the windshield coating may prevent the devices from working correctly. I just wanted to check if anyone has successfully installed a detector and hardwired it, and if so, how/where (on the windshield), and do I need to purchase anything additional to allow it to work?
Thanks for your help/advice.
