I went with concealed method and my button is in the Center armrest.

 

I also put it in the center console.

Randomwalk, you just need to put the button where she won't find it (like under the seat)

 

I'm in with Henry as well. He installed my ipod adapter and it works great. Hopefully will be doing the nav override soon.

 

I have found your comments very encouraging.
I have two questions.
1) Do you know if it is possible to install the PS in a SC430.
The actual navigation unit is in the trunck so I am not sure about accessibility.

2) Do you know if anyone has successfully created a 5.1/10.1 hybrid disc. I have been trying but so har have not succeeded.

 

rx and gx both have nav ecu in the trunk as well

not sure about hybrid disc though

but since you have gen4, you don't have the hidden screen anymore with the finger dance? coz' you updated to the latest version?

 

Since I have beige interior, I have installed the PS unit switch on the passenger side just underneath the dash at the edge of the black trim. Hidden but easily accessible.

 

Actually I do still have the hidden screen with the override becaus I have not yet installed the new disc.
I called Prstigiou and they indicated that they do not sell a unit for the SC430.
As a result I am looking for someone who has had success creating a hybrid disc which would allow me to retain the override
