How to add USB adapter to Avensis T27 with W53828 CD stereo


Description

Adding after market USB adapter to W53828 in the Avensis T27 using the vacant Cd changer port at the rear. <br />I installed the LaPower USB/microSD/Aux/Bluetooth adapter, bought on eBay.

Having use USB memory sticks on my Mk1 Avensis with Sony, CD changer and Connects2 for many years, I wanted the same on my T27. 
My original post: http://www.toyotaownersclub.com/forums/topic/169513-added-usbbluetooth-adaptor-to-w53828-in-avensis-mk3/
 
I choose the LaPower Adapter as it had the additional Bluetooth A2DP, at a cheaper cost than the usual Connects2 and Xcarlink, plus the supplier is UK based.

The trim removal kit  P1070875.jpg
 
The first is to look at the many guides for the radio removal on the internet. http://www.handsfree.lt/index.php?route=product/download/download&download_id=13
 
Remove the glovebox. 
 
With the trim removal tool I obtain from eBay I carefully worked on the top vent.
 
  P1070855.jpg   then the passenger side trim near the heater controls. 
Then remove the surround to access the lower screws securing the stereo P1070858.jpg .
P1070859.jpg. Remove the four screws to access the rear of the stereo. Pull the stereo forward and slightly to the left to pass the right trim, which is only loosened and not removed.
Looking at the rear the Cd changer socket 12 pin (6+6) should be empty  P1070843.jpg  .
P1070844.jpg Route the cable for the adapter from the glove box area, as close to the firewall as possible, behind the vertical reinforce bar and insert into the CD changer socket.
 
At this point, reposition the stereo and connect the adapter to the cable. Get a memory stick with music and test the system. I used mine from my other system and they all worked fine. Better to find out now than later after putting the car back together. 
 
I decided to leave the adapter in the glovebox for now P1070873.jpg but may make changes.
Next was to install the microphone P1070876.jpg and carefully rand the cable along the front of the roof lining, tucking along the front of the A pillar close to the windscreen - this avoids interfering with the curtain airbag!
 
Everything was put back and the sound quality is very good and clear. Most of the functions can be operated by the steering wheel controls. I have two mobiles and the second is connected to the adapters Bluetooth. Calls can be taken or rejected by the steering wheel Next or Previous buttons. The other phone is connected to the cars Bluetooth.
 
I may get an USB/Aux extension cable and mount in a blank hole in the dashboard tutorials-76861-0-00319900-1442736166_th
 
tutorials-76861-0-37945100-1442736255_th measure the blanking plate and compared to measurements of the two I found. They both measure the same 33mm x 21/22mm  tutorials-76861-0-44846700-1442736104.jptutorials-76861-0-16006400-1442736132_th
 
The first costs £11.80   http://www.ebay.co.uk/itm/121504852123?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
 
The second £5.88 http://www.ebay.co.uk/itm/391206888063?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
 
The first looks better built and seems to match the hole, whilst the second looks cheaply made and may need more work to keep in place.
 
If I go ahead, there will be an update.
 
I bought the more expensive USB/AUX dashboard extension cable because it looked a better fit, and I was correct.
 
tutorials-76861-0-78846100-1443087152_thtutorials-76861-0-78959900-1443087169_th The socket without the cable attached.
 
The blank socket I chose was close to the steering wheel tutorials-76861-0-71095000-1443087509_th 
 
A notch had to be cut out on upper right side of the hole, using a craft knife. A slight adjustment was done on another notch and the socket now fits perfectly. The dashboard material is soft and easy to work on. 
After routing the cable, repositioning the adapter to the space behind the heater on the passenger side freed up the glove box. If the adapter needs resetting, removing the glove box gives quick access. 
 
tutorials-76861-0-55360300-1443087292_th  The USB/AUX socket in position. It looks a lot better now, but I may move it to the storage compartment between the seat replacing the original socket tutorials-76861-0-66103500-1443089060_th.
This will need a lot more work and I could not remove the reverse collar on the gear stick. I don't want to break that!
 
The system works well and I will not be using the microSD socket on the adapter, only USB memory sticks. The adapter can only use one or the other, so it is not an issue.
 
The total integration is very good and the only minor gripe which is for every USB adapter, is the lack of artist/title display. I don't really look at what artist is playing, since I put the music on the USB stick!
 
Unfortunately iPhone and iPod are not supported through the USB cable, but I don't own or use Apple products.
 
A cheap upgrade.  

 

I have changed the position of the USB/AUX dashboard extension, to the centre storage box. This replaces the AUX only socket which is not needed. tutorials-76861-0-67181900-1443253171_thtutorials-76861-0-09643400-1443253190_thtutorials-76861-0-11299600-1443253210_th As you can see, both sockets look identical and the fitting notches are in the same location.

The later Avensis has the USB/AUX in the same position in the centre storage box tutorials-76861-0-38160800-1443260352_th

 

Removing the centre console covers is fair simple. 

First the covers between the dashboard and the console tutorials-76861-0-43866500-1443260570_thtutorials-76861-0-31664900-1443260797_th and the console surround trim tutorials-76861-0-03374200-1443260759_th. Remove the lower console trim in the footwell on both sides.

 

Then the gear lever console trim. Press on the gear lever cover surround to separate it from the trim and using a suitable lever lift the trim. tutorials-76861-0-97533800-1443260857_thtutorials-76861-0-50194600-1443260909_th tutorials-76861-0-97224800-1443261766_th.

 

Also remove the ashtray and lighter panel to re-route the adapter cabletutorials-76861-0-22978000-1443260955_th.

 

Now with the access you can unplug the AUX socket and remove ittutorials-76861-0-55639000-1443261001_th tutorials-76861-0-67480200-1443261045_th

 

Install the AUX/USB socket and route the wire from the adapter carefully to the socket. 

 

Refit all panels in reverse order.

 

Job done.

Hi Konrad

Thank you for all the information that you have provided. I have the B9010 unit and I have followed your guide fully, and purchased the same adaptor and installed it.

I have 2 issues which I hope you could give some advice on..

1) Via bluetooth all car speakers work fine, but the quality is poor (both music and calls) and I therefore prefer the aux option - however, anything played via the aux the audio is only played from the right speakers of the car. I have tried everything, and there is no way that the sound will come out from any other speakers.

2) All of a sudden (after few minutes of playing anything via aux or bluetooth) the CD changer screen will disapear, and it will no longer work. pressing the DISC button (to change it from CD to the CD changer) stops working. So there is no way to get it back to accessing the adaptor. I have no clue why this happens.

Usually a call will last 20 seconds and then the the audio system will just turn off (as it cannot access the cd changer option). The only way to get it working again is to turn the ignition off and on again. Then everything resets and then it plays BUT the same problem will repeat.

 

Is there a chance that the extension cable is faulty? That runs from the adapoter and out the dashboard? However, the turing off issue still persists with bluetooth which has no connection to the aux cable and the extension. 

I would areally appreciate if anyone can help with this issue.


Thank you guys!
