Fixing Voice Navigation on my Toyota Navigation Unit
Posted by: Kristian In: Cars|Do-It-Yourself
Apparently, my 2004 Sienna JBL Amp was not 100% compatible with the Tundra’s E7006. Once again, eBay saved the day. To handle voice navigation, I discovered that I needed a 86280-OW420 JBL amplifier. I bought this amp on eBay, swapped out my old amp with this new one and it works beautifully. So now I have a Tundra Nav unit with a JBL amp from some other Toyota working nicely in my Sienna.
Here are the steps I took to swap these out.
1. I found the location of the amp behind the glove compartment.
2. After I carefully removed the glove compartment, I could see the amp.
3. The amp connectors are oriented towards the bottom. I disconnected the connectors from the amp. It was very tight in there and I needed need to cut some of the tie binders to allow some more flexibility, after which I could remove the amp.
4. After I took out the amp, I laid them side-by-side. They look identical except for their brackets.
5. Once I put the 86280-OW420 in, I had to pull a wire for the voice navigation:
6. Connect Pin 11 and Pin 13 respectively to …
7. Pins 23 and 22 on the 86280-OW420 amp.
I put everything together, and voice navigation works!
