I'm new here and I have a question about the placement of the IR heads.
I have a 2011 BMW 528i and it's a bit tough to find a proper location for the M27 heads. I heard that it's tough with BMW's in general. I've searched some BMW forums but I can't seem to find a good thread on this matter. It's mostly self install threads with no concrete performance updates after the install.
1. Can the heads be installed vertically on the slats of the grill and function properly? I've read in many posts here that the heads need to be installed horizontally with the receivers towards the outside.
2. How about behind the grill? I've done some search on this matter but I hear both sides... Some say it works fine and some say that it will deteriorate performance quite a bit.
3. 3rd option would be under the chin of the spoiler out in the open... I'm guessing that's too low.
I don't have enough posts here so I cant attach any pictures yet. Can you guys search for an front image of a 2011 BMW F10 5 series and let me know what you think?
It would make sense to mount under the plates but it's a very shallow lip and I don't think it can be mounted securely. The blank space under the bumper (what looks to be blank) has a diamond pattern black plastic grill (about 1/2" hole on each diamond) and I'm not sure if installing behind this grill will clear the IR signal with minimal interference.
I'm having it professionally installed but I wanted to have some foresight on the location so I can confirm/agree with the installer.
Thanks for the input guys!
