A little misunderstanding here....
The CL that was featured here was relocating the OEM navi unit from the trunk to the front passenger seat like the MDX. He was also doing a full stereo upgrade and he was adding dynamat to all the interior panels to reduce noise and vibration. Sorry if the pics scared you the top pics were for something else. I have the navi modification which I use if I want to watch videos, I am in the process of installing two 8 inch monitors plus a 6.5 flush mount flip down monitor for the third row(the whole roofliner will be rebuilt and customized). I am just waiting for some extra $$ to come in, courtesy of Uncle Sam. I should have more pics soon, this will include the 3 JL audio amps installed on the 2nd row seats(recessed into the backside), I am also upgrading my 2 JL 8W3 to 2 JL10W3, still mounted on the cargo area except it will not be flush to the floor as on the 8s, 2 Kenwood amplified 5.5 subs, underneath the 2 font seats, the PS2 installation, ceiling mounted tweeter for the rear passenger front surrounds, rear surrounds in a customized pod in the rear A pillars(located above the 3rd row seatbelts). If I have any left over $ I might add a few 1/3 octave EQs(PPI or Phoenix Gold) they will be recessed into the 3rd row in the same fashion as the amps.
