Looks great man.
I have a Pontiac (grand am) and I was thinking the same thing for mounting a touch pad. im guessing (hoping) that the size of our little round cup holders in front of the shifter are the same size, which would help me so I can just get the one you use
Also, we probably have the same amount of room inside the armrest! Do you have install pics/directions possibly? How/where did you run the wires? This might be a great summer project, with your help, I can probably pull off the same setup in my armrest...thanks for the idea!
Let me know..
