Installation Instructions Apply to All Applications Listed Below

Many of our previous customers discuss their installation procedures on message boards.  Please visit our message forum, siennaclub.org, toyota-4runner.org, and tundrasolutions.com.  There are tons of helpful tips on these sites.

The 2006 Camry Navigation unit will also work for most if not all 1990-2006 (7 1/16" size opening) Toyota Vehicles that are not listed above, however a slight modification to the dash opening will have to be done in order for the Navigation to look flush with the dash.  Please click here for more details.

Quick note:  This Navigation unit does not use an external "box" or ECU like many other Toyota Navigation systems.  This is an all in one unit.  The ECU (DVD Drive) is built into these units.  The stock 2002-2003 Camry, 2003-2004 4Runner, 2004 Sienna Navigation units use an external ECU which is located in the rear of the vehicle.  The Camry and Solara Navigation units we sell can be retrofitted to these applications instead of using the actual Navigation unit made for the vehicle.  What's the advantage to using the Camry or Solara unit?  To install an actual Sienna, 4Runner, older Camry unit from scratch would mean running wires all over your vehicle from front to back between the head unit and the ECU.  Not to mention we can only get a hold of Camry and Solara navigation units which means you'll end up paying a much higher price, approximately $5,000, for a Navigation system that is more complicated to install.  The Camry and Solara units allow the customer to maintain the stock feel of their vehicle without paying retail prices and spending countless hours on installation.

(IF you already have the JBL sound system installed, skip this part) The external amplifier may be the hardest part of the install as you'll need to find a place to mount it.  It currently has mounts for a 2002-2004 Camry but they can be removed.  Most of our customers who do not have a Camry, find room for the amplifier in the glove box.

(IF you already have the JBL sound system installed, skip this part) The jumper harness included will connect to the present 10 and 6 pin plugs that are currently connected to your old stereo.  The other end of the jumper harness will connect to the amplifier and the Navigation unit.  You shouldn't need much further instruction than that for connecting the jumper harness as once you see it, you'll realize it's pretty self explanatory.

(IF you already have the JBL sound system installed, skip this part) There is a black/white one pin plug on the jumper harness and this is your ground wire.  This wire can be spliced and connected to anything metal that leads to your vehicle's chassis.  You should be able to find a bolt that leads to the chassis very easily. You will not fry the amplifier if it is not grounded correctly.  The amplifier will simply not turn on and you will not hear any sound until it is grounded correctly.

If you already have the JBL sound system installed, your current plugs on the rear of your existing stereo will transfer over to the Navigation unit.  Yes, this also includes steering wheel controls and radio antenna.  Once all of these plugs are transferred, you will have power to the Navigation and output to all speakers.  Next is connecting the GPS antenna.

The GPS antenna can be mounted anywhere you find room.  We strongly recommend mounting the antenna behind your rear view mirror.  When mounting the GPS antenna, we removed the metal bracket which had two Philip head screws holding it on, then mounted it with the WHITE LABEL on the GPS antenna facing up and the mirror surface facing the stem of the rear view mirror.  DO NOT touch to reflective mirror surface on the back of the GPS antenna.  The GPS signal is much stronger if the antenna is in a visible area.  Be very careful not to route the GPS wire anywhere the wire may get in the way of an air bag.  The GPS antenna extension wire included in the package is over 15' long, so don't worry about the antenna not reaching your ideal location.

After the GPS antenna is mounted, click on the "DEST" button.  The destination menu appears.  Notice on the far left of the screen there is a picture of the North America continent.  Touch the "Change" button to select your region.

Once your region is selected, drive around your area until you receive a signal.  Whatever you do, DO NOT manually calibrate the unit if you do not receive a signal right away.  Drive until you get the signal, it should only take around 3 minutes at the most.  Once your location is zeroed in, the GPS will accurately keep track of your vehicle's position.  If you shall ever lose the GPS signal (under a bridge, underground parking), the speed sensor will help compensate for the loss and then find your exact location when the signal is regained.

The last step is installing the speed and reverse sensor wires.  The speed sensor wire tells the Navigation unit how fast you are going so it can keep track of your location if the GPS signal were to be lost.  The voice navigation and auto-reroute function will also not work until the speed sensor wire is connected.  The reverse sensor wire tells the Navigation unit when you're in reverse, this way it knows to show you going backwards instead of forwards.  You'll also need the reverse wire connected if you decide to get a reverse camera which displays everything behind you on the Navigation unit's screen.

Extra instructions for the Solara Navigation unit ONLY - Does not apply to the Camry model.

The Solara navigation unit uses an extra channel for voice navigation that is not recognized by the 2004 Tundra, 2003-2004 4Runner, and 2004 Sienna PREINSTALLED JBL amplifiers.  In order to acquire voice navigation from this channel, you'll need to add an amplified speaker.  Recently one of our customers, a master technician from Bossier-Atkinson Toyota, took some time to write out his install instructions for us, to pass onto our customers.

All of these items were purchased at radio shack for $40.00.  I soldered a 1/8" stereo plug to the +(pin 11) -(pin 13) coming out of the navigation unit (20-Pin plug - plug E on the picture of the rear of the unit located at the top of the page). I then found a pair of amplified speakers for use on a home computer (item# 4001446) that operates on 7.5 DC. Next I used a universal 12 volt DC adapter (item# 2731810) to reduce the voltage to 7.5 volts. The next step was to install a power outlet (item#2701556) to plug the 12volt adapter into (wired into the back of the factory power outlet for switch power). Then it was easy:

• Remove the passenger seat and install the speaker to the carpet with a zip tie. There are 2 speakers in the kit, but I removed the second speaker since 1 was loud enough & easier to find a home for.



• Run the power & speaker input wire under the center console towards the dash board. 



• Plug in the 12 volt adapter to the new power out let mounted under the console.



• Plug the wire into the 1/8" stereo jack coming out of the Nav unit. (recommend using a shielded 2 wire cable with the shielding grounded to the navigation unit to reduce ignition noise. I did not do this, with the speaker under the seat I could not hear it, but it was slightly noticeable) 



• Re-install the seat & console.



• Go for a road test to adjust the volume to your preference

Where to insert the two wires into the 20 pin plug

Looking at the rear of the 20 pin plug (back side with wires coming out), this is how the pins are numbered - Speaker taps are cyan:

With the two wires/connectors OEMValue provides, insert them into pin slots 13 and 11. Add a ground loops insulator (item#270-054) if there is a hissing noise coming from the amplified speaker.

After Market Amplifier Installation

Some of our customer's choose to install their own after market speaker amplifier.  First thing, make sure the amplifier is a four channel amplifier.  A four channel as opposed to a two channel amplifier will give you much better sound quality and will fully utilize all four pre-outs on the 2005 Camry Navigation System.

The jumper harness supplied will have all the necessary wires to supply a clean signal to the after market amplifier.  The single shielded wire (dotted line) is the ground (-) for all four outputs. The colored wires are positive (+) and represent the ACTUAL color on the jumper harness.  RCA plugs are available at your local Walmart or Radio Shack in the car audio section.  Refer to the Camry wiring diagram if the picture of how the wires connect to the RCA plugs below is unclear Click Here to View. 

Speed/Reverse Sensor Plug or Wires

To connect these wires, you'll need a wire schematic of your vehicle.  They can be found in shop manuals that are created specifically for your vehicle.  Please write us an E-mail we may have one readily available.

IF speed and reverse sensor wires were not available when you made your purchase:

You will need to purchase the following cable from Newegg.com:

GENERIC AUDIO 24" 4-pin Connector Cable Model 11A1-12418 - OEM

You will then need to extract the two pins from the audio cable by cutting off the plastic molding to expose the pin connector.

How to install the Speed Sensor, Reverse Sensor wires:

The wire located on the far left (wire #5) is to be connected to the reverse switch.  The wire on the right (wire #3) is to be connected to the speed sensor/speedometer.  If you can acquire a diagnostics manual from your local dealership, refer to the combination wire assembly.  From there you can find out which wire goes where.

Reverse Camera (not included)

Many of our customers decide to add a reverse camera after they have finished the Navigation install and have confirmed everything is up and working correctly.  Most kids, animals, and smaller objects directly behind your vehicle simply cannot be seen with a normal rear view mirror.  The reverse camera assists the driver in backing up and covers the blind spots that cannot be seen with a normal rear view mirror by displaying the surroundings on the display of the Navigation unit.  In the long run, this is a great accessory to have as it could save you thousands of dollars from preventing accidents or even endangering someone's life.

For a plug and play camera, we recommend the Eclipse BEC104 reverse camera.  Type "Eclipse camera" on www.ebay.com in the search bar and you can see what they are selling for.

We went ahead and purchased the HQ Keyhole Rear View Camera from Yan Laboratory Electric Science and Technology.  Camera arrived in 3 days via Airborne Express.  We will post install instructions for this particular camera soon...
