Just wanted to a share a trick I came up with while installing a Kenwood head unit in my 2012 F250 XL. Being an XL package I had a Plain Jane AM/FM radio which got old pretty quick. I picked up a Kenwood DPX303MBT from Crutchfield with the pre-made wiring harness and a Metra mount kit and had the whole thing installed in an hour. The hardest part was figuring out a place to mount the Bluetooth microphone which picks up your voice when you take a call through the radio. I decided to mount it high on the windshield near the headliner which meant I had to hide the wire in the headliner, A-pillar trim, and the dash. The gap between the windshield and these items is rather large so I couldn't just stuff the wire in as it would fall right back out. I needed something to stuff in over it that would stay in place, so I bought some of this at Lowes:



It's caulk backer rod which is used to caulk a gap when there is nothing behind the caulk to hold it. Since my truck has the work package cloth seats and charcoal interior the color actually matched pretty well, but you don't see it at all. I just started at the headliner right next to where I had mounted the Bluetooth microphone and started stuffing until I got all the way down the A-pillar and into the dash:





By the way, right below the tray on the dash there is an opening through which you can pull the Bluetooth mic wire (I fashioned a hook from a coat hanger) in order to connect to the head unit.

 

Great idea!!! Going to try this tonight. Thanks for posting.

 

You probably never thought your post would help someone out 5 years later!! I saw this last night while scouring the internet for the exact answer to my problem with my Kenwood Head Unit Blu tooth MIC routing. I went to Lowe's this morning and got it squared away!! Thank you so much for posting this!!
