I have had the Seicane 9" screen version installed for sometime. Thought I should recap the install.

I chose to use the same route to the rear as I did when I installed the Mediabridge. I went down the driver's side behind the console side trim. I lifted the carpet at the seam under the driver's seat and routed the cable to the side trim under the door. I removed the trim pieces under the front and rear doors and slide the cable under the carpet. I pulled the bottom out of the plastic trim between the front and rear doors to get the cable under the carpet around the door post. The only upholstery piece I removed to do the install was the small piece on the driver's upright portion of the rear seat, from there it is easy access to the rear.

For the backup camera I tapped into the wires at the front for power. I ran the wire for the backup that is on the Seicane harness to the corresponding camera wire in the rear and grounded the camera in the rear compartment. I install RCA splitters so I can activate the camera when not in reverse connecting them to video in on the unit. I installed the camera in the center of the pullout piece where the trailer hitch goes. I drilled straight though the plastic to get into the rear. I used a grommet and silicone to seal the access. Camera is the Sony camera offered by Seicane.

I added a USB hub so I could add a phone charger line. There are only two USB on the unit. I had to remove the IBUS app with DSP. IBUS alone works fine. The DSP portion was a second equalizer conflicting with the equalizer in the Seicane.

In the initial install I only had sound for 20 seconds. After many attempts at correcting the problem I took it to a custom audio shop. It wasn't just one issue it was several that when combined required the experience of several techs to unravel. One problem was my DSP amp that I ended up replacing. If not for the DSP amp malfunction I think it would have been a fairly straightforward install.

Seicane instructions and tech help are useless IMO. This thread was very helpful though no one had the same unit and DSP so suggestions were not always applicable.

After all the problems I am still very happy with the Seicane. Great upgrade! Sound quality is much better, like being able to use torque and several other apps. Like the included navigation.
