This is good information. I have a 2006 new Tundra Access Cab Limited that was supposed to come from the factory with a navi system but didn't. The dealer without approval took the liberty of installing an after market Eclipse 5435 unit and also kept my stock equipment. What was in my truck (that the dealer removed) was apparently non JBL. (I didn't notice this for a week because I work a lot)

I can see under the rear passenger side seat where the amp was and where they spliced the wiring for the Eclipse unit. I am determined to install a new Toyota JBL E7009 navi unit I purchased. I can obtain a JBL digital amp(necessary) but am pretty sure the wiring is going to be a challenge. I have also read the Sienna forum where there is good info on the install of JBL navi HU.

Any idea on next step or advice. I am willing to pay a pro shop to do the work, but I want to be sure it is done right. (I already have $4K invested, what's another $1K)
