How To Program Nav While Driving Mod 2009 Navigation
--------------------------------------------------------------------------------
Step by Step on how to do the mod so you can program your factory nav unit while driving. It is pretty easy to do. I installed the switch in my glove box so it is out of sight and will not get bumped by accident. I did this on my 2009 Titan Crew Cab LE. The wiring harnesses are different than previous years but it is the same wire you have to cut (white with red stripe). If you follow this step by step you will not have any problems. I bought all supplies at HD for under $20.
What you will need: 1 Single Pull Single Throw (SPST) toggle switch, 4 wire crimps or nuts (crimps are neater and take up less room), 2- approx 7' lengths of wire (or speaker wire will probably also work) I used 16 gauge, philips head screwdriver, wire crimper and cutter, zip ties & exacto knife
Step 1: Move passengers seat all the way forward to access protective cover for the Nav DVD Player.
Step 2 & 3: Remove both screws in the cover and remove protective cover. Slides up and off.
Step 4: Rear view of Nav DVD player. Locate wiring harness on the right, of the big unit.
Step 5: with thumb push down tab in the middle of the harness on the right and pull back, be gentle but comes out with ease.
