Yes, it was required to access the passthrough for wiring. the bottom seat snaps off, but the backrest requires 3 bolts on top and four on the bottom of the seat..

 

OK thank you for the info.

 

Quick update for everyone. DVD bypass is killer. Everything works great. However, I had two things that led me to return the NAV bypass.

1. I just hate the factory NAV system. It's clunky, not user friendly, and not up to date. I am not going to buy updated maps when I already had a Garmin with lifetime updates. My Garmin now lives again in the LS.

2. I believe I had some sort of problem with my bypass module. It worked great, until I turned the car off and back on again. Once I cycled power I would have to press the button to deactivate and then reactivate the bypass. Problem is I didn't mount that switch to the dash (cord wasnt long enough and I was too lazy to do it). I called beatsonic and they were super cool. Said it shouldn't do that and given my lack of intention to use the NAV anyway, they gladly accepted my return.

Overall two thumbs up to Beat Sonic. Now I just need to install the rest of my stereo system. Lol

 

Where did you get the dvd bypass?? I need this!
