connecting your iPod Touch or other MP3 player to your car can be a real problem. RF car adapters often have poor sound quality, tape adapters are of poor quality, and require a tape deck (which many newer cars do not have, including the 9th Gen Toyota Corollas that ran from 2003 to 2003). 2008) and AUX audio input adapter kits can cost upwards of $ 75. Here’s an alternative method of connecting your iPod to your car; You can manually add an auxiliary input to your car stereo yourself. A 2005 Toyota Corolla with a single disc CD player is used as an example, but this technique works for many types of stereos.
Step 1: connect auxiliary cable to stereo
Section 1 (Steps 1-3), Remove the Toyota Corolla Stereo: Insert a flat screwdriver under the plastic base of the gear lever to lift it up. You don’t need to disconnect the cigarette lighter wires and don’t mess with the gear stick. This piece simply needs to be moved around a bit to get the other pieces out of the panel.
Step 2: 2005 toyota corolla radio
Remove the center control knob (fan speed) from the instrument panel and loosen the screw that is hidden behind it. The entire instrument panel opens as shown in the picture. Again, don’t worry about disconnecting the cables as they are long enough to move the panel out of the way to get to the stereo.
Step 3: Toyota Corolla stereo connection
Behind the control panel below the stereo are four 10mm screws that mount the stereo to the dash. Remove them and pull out the front and stereo vents. Carefully remove the antenna and speaker / power connectors from the back of the stereo. Slide the vent assembly out of the stereo. Be careful not to scratch the instrument panel when removing it.
Step 4: how to add auxiliary input to a stereo
Section 2 (Steps 4-11), Disassembling the Stereo and Soldering on the Auxiliary Input for iPod: The stereo assembly consists of a CD player and radio with amplifier inside a metal frame that has brackets attached to place them on the car.
step 5: put auxiliary input to radio cd
Begin disassembling the stereo by removing the eight bolts that hold two mounting brackets (marked L and R). The front plate of the stereo is broken; Carefully disconnect the two ribbon cables that connect the faceplate to the stereo body.
Step 6: my stereo has no auxiliary input
Remove the small screws from the top, left, right, and bottom of the metal case assembly. The top slides off first, followed by the sides and bottom.
Step 7: how to fix an auxiliary cable
Remove the CD player by removing the two small screws on the front (where the faceplate was). There are “CD” marks next to them. Carefully disconnect the flat cable connecting the CD player and the stereo body.
Step 8: toyota corolla stereo
Think about the way the CD player interacts with the rest of the stereo. The cable connecting the two should control the CD player and carry the audio output of the CD. Look for clues on the CD player’s circuit board to find which points soldered to the connector provide these functions. For the 2005 Toyota Corolla with a single disc CD player (A51813, model number: 816120-02430), the CD player cable has 14 conductors (or vias) and each is labeled on the circuit board of the CD as follows: 1 = n / a, 2 = SW1, 3 = n / a, 4 = n / a, 5 = n / a, 6 = RESET, 7 = n / a, 8 = SIMO, 9 = SOMI, 10 = SCKM, 11 = SW3, 12 = LCH (for left channel), 13 = ACOM (for common audio), and 14 = RCH (for right channel).
Step 9: stereo input
Cut the extension cable from the headphones (keep the side with the male connector from the headphones) and strip the three wires. On the cable I used, black was the audio common (ground) and red and white were the left and right channels, respectively. The tape that connects the CD player to the body of the stereo plugs into a bulky connector that is soldered to the main board of the stereo with large pins, the perfect place to solder. The leads of the cable are labeled on the CD player, so follow the path of the LCH, RCH, and ACOM along the cable to the main board connector to find the correct pins as indicated in the diagram below.
Carefully solder the RCH, LCH and ground headphone wires to the …
