Noise from Aux Port (06-08)

Thanks!

I've attached a pdf for your review. Basically the front and rear of the center console pull off. I don't think you need to remove the entire unit to perform this upgrade.

Thanks much! Exactly what I was looking for...

Just finished the install...took me about an hour and change. I was wrestling the center console for awhile..taking forever to try and effectively get at the aux adapter piece. I didn't/couldn't take off the rear part of the center console, but the front pulled apart pretty easy.

With the screws removed from the front part, the two bolts under the carpet of the center console allowed the unit to lift up to where I could reach underneath and unlatch the adapter, pushing it forward INTO the console. At that point it took about three seconds to hook everything together, but there was absolutely no room to tie the wire and condenser to anywhere...without making the drawer completely unable to shut. I left things loose under there. As it turned out, the little drawer shuts about 98% of the way...not 100%.

I don't know how the techs at Toyota are supposed to make it fit cleanly... But I plugged my phone into the 12v charger, hooked in the AUX port...and the silence was deafening!!! The music sounded nice and clear...no squeaking or crackling while plugged into the charger.

Thanks again Mylar.

Recently purchased a 2009 and in the first week of using the aux input I ran into this issue to the point where I couldn't stand to use the aux input while plugged into power due to the feedback etc.

Read all the threads confirming that 2009 had the same issue even though no one knew of a TSB that included the 2009 models. A quick search of alldatadiy shows me that there is an updated TSB that includes 2009 Prius:
SB0067-08R1, released on 11/19/2009. Take that with you to the dealership if your car is still under warranty.

Mine is 1k miles out of warranty and not sure if it's worth the hassle or if I should just get the parts and install on my own or just go ghetto with an inline ground loop isolator etc.

Anyhow - thought I would share the fact that 2009 IS IN FACT included in the TSB. The disappointing thing is that while 4Runner and Prius had the issue from 2006-2009, other models included in the TSB appear to have resolved the issue after 2008 or earlier (Camry, FJ Cruiser, Rav4, Solara, Yaris). Not sure why Prius got the shaft with this one.

Not sure what the etiquette is on this board - I toyed with creating a new thread to include 09 since this one's title is specific to 06-08. Anyway, this tidbit is here, just buried 10 pages in - at least I won't get flamed for starting a new thread unnecessarily ;-)

Could someone that has access to SB0067-08R1 post it here? Thanks!

This is the text from the alldata version of the TSB. Format isn't ideal and images are missing. To be honest, I think it's exactly the same as the old TSB just updated to say it applies to 2009 Prius as well. The parts are the same for Prius and they still use 2007 model as the example in the steps.

Here's the text:

Just did the TSB myself (out of bumper to bumper warranty) - 30 minutes and $148.00 later, complete silence when listening to iPhone while it's plugged in.

Here is another solution that worked for me (plug and play, $US 17.99):

127SNI135 PAC SNI-1/3.5 Noise Filter solves AUX input issues

Does this noise happen only when the music player is plugged into the cigarette lighter for power, or does it also happen when the music player is running on its own battery?

According to the TSB and from my own experience it is only when your device is plugged into power:

"Some customers may notice noise in the auxiliary mode of their audio system when using an MP3 player or other external audio source with a charger connected to the 12V power port of the vehicle."
