Its the same car right up until 2010 armada in terms of this add on accessory.
Any competent radio shop can install this. Bestbuy, local car shop, etc. there is lots of forum talk on this here, so if you are good at this kind of thing, you can purchase an aftermarket system and install yourself.
On the vehicle I had prior to purchasing my new '17 Armada, I had a Viper 2-way LED remote start system installed by a local car stereo shop. The remote start system was fantastic. I could start my car from the 5th floor of my office building and have it all warmed-up/cooled-down by the time I got downstairs to the parking lot.
I actually had a shop install it for me , it has a proximity sensor you when you walk up the car it senses the keyfob and unlocks the doors. They did remove my key mechanism and put the pushbutton over the hole.
This car is what I look like on the inside. To view links or images in signatures your post count must be 10 or greater. You currently have 0 posts.
