I've been using a V1 for nearly a year already, but in the past week I've noticed funky behavior.
I still seem to pick up sources well enough, but as sources go from front to rear, the arrows don't work properly.
For example, as I drive past the same CVS I have since December, the arrow stays pointing forward past the shop, or it points to the side, but not always behind. Today, passing a photo van on the opposite side, I picked up his radar, and then as I passed, it kept pointing to the side but not behind.
I realize that it could be something as simple as the signal not being strong enough to trigger the rear sensor as I drive past, but two things have changed this week:
1. I had the car tinted. 35%/15% but I paid for nanoceramic which isn't supposed to interfere. I could suspect the shop put cheaper stuff on to make extra $$ because I'm not sure how to prove it
2. I took down the RD for the install, so nobody would be tempted. I put it back up in the same location, high on the passenger side above the RVM. But maybe I put it too close to the mirror or something to interfere? I can't be 100% sure it's in the exact same position.
Any advice? It's almost due for a tuneup anyway, maybe I just send it in?
