I made mu remote garage opener a built-in device in My Outlander 2008. I found a lot of space above the switch cover on the front dome light, removed the cover (snap in, just careful, do not damage while prying it off), drilled a hole for a instant on switch, soldered my remote, put it between the roof and the dome light and snapped back the cover... Voila, no more garage opener in my pocket...

that looks pretty slick! well done.

where did you get the button? it looks nice.

 

awesome, might consider something like this. In the mean time I bought a small garage opener and placed in the lower storage compartment. It's hidden and still have easy access.

 

pretty clever

 

Isn't that where the BT interface mic is located?

 

Indeed, but I do not plan to add/use the BT at all...
The push button switch was purchased in electronics shop (similar to Radio Shack) in Vancouver ($2.99)
Thanks all for comments.

 

Nice job!!!

 

Actually, I just added the BT module and the mic is not affected with my push-button switch. The switch is located in the area where the sunroof switches would be installed on a model with the sunroof.
