Socal member just installed my ALP and V1 in BMW 135i

[Hit redline]

Hi & Welcome to the Forum.
Rest assured,the AL Priority performs far superior to LI & Blinder parking Sensors, I've owned (& tested all 3 Models).

Regarding your install:
Your V1 location screams "look at me- break my window & steal me" to a thief.
Your Sensor pix is to far recessed which will make you a sitting duck from an Overpass shot. Also, it may be an optical illusion but the Sensor looks pitched upwards 3-4 degrees...that's not good.

No worries for the V1, my windows are tinted pretty dark including the windshield with black interior make it hard to see.

Thanks for the advise on the sensors. They are level so must be the pic angle. In CA I have yet to see one shooting from an overpass, always on the side of the road some times using barriers or bushes to hide.

Also just an FYI regarding mounting horizontal and vertical. On a BMW forum a guy has the ALP with one sensor mounted in the grill vertical, says he has had it tested and works with no issues. Thoughts?
