Below is my comment on another thread.
I put a Lockpick from Coastaletech in my 08
[COLOR=#ff4400 !important][COLOR=#ff4400 !important]Sequoia[/COLOR][/COLOR] which has the same dash as the Tundra. It works well. No wires to cut. I was amazed at how easy it was to pull the Nav unit out. Once you get the NAv out the install is idiot proof and easy to undue.
Their instructions don't tell you how to pull the nav unit out only how to install once out.
One other thing is it seems the audio system must be on for it to work. It will only work if the CD/Radio/Sat is on. If it is off so is the lockpick.
The Lockpick also shuts down the nav tracking when on. So if you are using the nav, it will be offline the short time it takes to put is say a phone number. When you are done the nav comes back and the gps have to relocate where you are which may take a minute or two. Don't use the lockpick if you know you need the nav to give you an instruction in the next minute or two.
The Lockpick is invisible to everyone unless you know it is there and how to activate it. I tow with my truck and it is nice to be able to turn on the rear camera to check on things while not in reverse.
I recommend it.
