Great Find:thumbsup:

I have added the original TSB to the "I survived Pairing my Bluetooth thread"

On edit..

When I tried the TSB procedure I noticed the following:

Once I saw "Not Linked" displayed I had to be real quick doing the "Vol up-Vol down, Vol up-Vol down, Vol up-Vol down press the tune knob' step

If I took my time I would hear "Phone Book" and "Vol Type" would not be displayed.

I also had to turn the TUNE knob to increase the outgoing call voume from the default "0" to "+2" not the VOLUME knob stated in the procedure

Sooo.. anyone else try this procedure yet? If so did you have to do the same thing I did??

I'm not sure whether we have a different system here in Oz as the above procedure doesn't seem to work. For one, we only get steering wheel controls for bluetooth with the satnav option. The bluetooth radio unit we have is shown below. Is it the same as the one the above procedure was written for on the US Highlander?

The steering wheel has to be on the left side for the procedure to work:D

On a serious note...looks like you would need to print out the TSB (the original TSB is here (http://mojavetrail.webng.com/T-SB-0097-09BlueToothMicVolume.pdf ) and ask your dealer to see if there is a Aussie version of this TSB. Looking at your picture your non nav system is completely different.

Thanks for the TSB Rykohl, and what timing!!! I had just returned from the dealership after leaving my HL overnight for a seat belt recall and to fix an AC vent which had fallen out of the ceiling. I had asked them to adjust the bluetooth volume, they said IT COULDN"T BE DONE:confused: . I told them I was sure it COULD be done, I was going to look on the internet. As soon as I got home I logged on and there was your TSB!

Yesterday I messed with it and now, finally, people aren't complaining of my voice being all choppy. I had to go from "0" to "-3".

The same service manager also told me all 5W 30 is synthetic.:rolleyes:

I might have to look for a different stealership.

Yep, I'd drop them like a bad habit. I've got two dealers/service centers within 10 miles of me, and one is terrible with a bunch of amateurs running it, and the other I have used for years and give the highest praise. Stealerships are definitely not all the same. Hope you find a good one soon.

I found the same thing - the TSB is wrong - the TUNE knob adjusts the SEND level as well, not the volume knob. Also, as Summerwind said - you need "Fingers of Lightning" to do this procedure before the "Not Linked" disappears. I set to (-2) as we were getting some clipping on outgoing calls.

I know how to do the other adjustments to guidance volume and also setting the receive ring/voice volume during an incoming call...AND even though the TSB says to adjust only the SEND volume, you do get the RECEIVE volume option as well when you do this procedure (with the +5 to -5 range)...it is defaulted to "0"

Not 100% what effect setting the RECEIVE volume lower i.e. -2 would have. Assuming it adjusts incoming voice and ring volume to a "lower level"... Does anyone know or is some "experimenting" in order?

The "fingers of lightning" phrase did it for me. I was getting so frustrated that the "phone" kept coming up. Then I tried to get my fingers to move like lightning and it worked! Thanks!

Does anyone know if this apply on the 2008 highlighter limited with Navi? I saw the note and it said
For vehicles equipped with the Toyota navigation system, please refer to the Repair Manual
procedures. I can't seem to find it.

Hoping for some help here. I have a 2013 Highlander (2nd gen and non-NAV) and I cannot seem to get these instructions to work.

I get to Step 4, and am long pressing the Off-Hook button (it is a long press right? Not a press repeated. The display briefly flashes "not linked' message -- when I say briefly I mean less than 1/2 second and it immediately searches for my phone ("Waiting for Bluetooth" -- and then goes into my phone display.

I have tried the Vol Up/Vol Down x3 action when not linked but nothing happens.

Do I shut my phone off? The instructions were clear the phone needed to be previously connected for this to work.

Very frustrating!

turning up mic

Forgive me--I am the most clueless person on this thread. I'm not a car buff; just someone whose callers can not hear me when I use my 2008 Solara's Bluetooth, especially if the top is down (yeah, I realize that's a problem.) Anyhow, I guess I need more explicit instructions, so I'm going to ask stupid questions.

1. By Turning on Ignition, you mean actually start the car, not just the aux power, right?
2. When turning it off, you still have leave it on aux power, right, or you don't get anything on the screen, right?
3. The "hook off" button is the obvious one with a phone off the hook, right?
4. I need to know what the previous person asked about whether to press the hook off button repeatedly or continuously

I can't even get to the "not linked" message yet.

Thanks for your patience
