Thanks for your input. I asked the installer to place it under the front passenger seat and remove the padding if necessary. I picked it up this morning. He was able to put it under the seat and under the carpet, but it sticks out several inches from behind the seat when the seat is full forward. The corner of the unit is exactly where you place your foot to enter and exit. Were you able to place the brain unit forward enough so that it is not stepped on? Even if it can take the abuse, the sharp corner is going to tear through the carpet soon. FYI: I installed an Alpine IVA-D300.
