Package with radio and parts

  • Porsche Radio Installation Packages

    From: $847.99

    Our radio package includes your choice of radio and all the parts needed to install that specific radio plus a discount.
    The package includes the radio, radio wiring harness, steering wheel programmer, plug and play converter, AM/FM antenna adapter, custom microphone and radio mounting kit.
    Just answer the questions and we will take care of the rest.

If you would rather purchase the parts separately they are listed below.

1. Radio Mounting Kit

 It is painted to match the finish of your dashboard.  Now includes the easy install brackets that makes installation much easier at no extra cost.

2. Radio Wiring Harness

Our radio wiring harnesses have a canbus reader to translate the can bus signals to translate illumination, switched 12V, reverse, parking brake and speed sense signal. We have 2 options, one for cars that use fiber optics for audio transfer to the amplifier and one for cars that do not. (read the technical info under these products for more info)

SRWH-997-MOST-HILO Fiber audio with an audio boost
SRWH-997 – Non fiber audio

Without fiber optic amplifier. 

3. Steering wheel controls (optional)

This wire translates your factory steering wheel controls for use with your new radio *when used with the harness above

Technical info about wiring harnesses

PCM 2.1 (Navigation Screen) cars will almost always have a fiber optic amplifier.  There are very rare early models that have a PCM but not fiber optic amplifier audio. In the hundred or so cars I’ve worked on and hundreds that I’ve sold parts to I’ve only seen it a handful of times.  CDR-24 cars usually only have fiber if the car has Bose.  Some Boxster and Cayman cars may have PCM and no Fiber. Even though the audio system is the same I do not see too many of them because until now we never added them to the site.  Put your vin number into the order comments and we can verify if your car has a fiber optic amplifier.

The small box on the main harnesses is a CAN-BUS data reader.  It reads for switched 12V, illumination, parking brake, reverse signal and Vehicle Speed Sense.  I have seen some 911 not provide VSS and I have seen a few Boxster models not provide reverse.  If they car does not provide it on the CAN-BUS data wires my box cannot provide it.

The large Box with knobs is our HILO box.  The box adjusts the audio levels going into the the factory amplifier.  Since different radios have different outputs and many of the numbers are not accurate this is important.  The box has four knobs only the front onew will l be used during installation.  And yes it will keep all your speakers just not the fader.  No adapter on this planet keeps your fader.  We also make the fiber harness without the HILO box. This will sound just about the same as factory. 

4. Plug and Play Converter (optional but strongly recommended)

Converts the connector on harness 2 into a connection specific to your radio.

5. AM/FM Antenna Adapter

This adapter converts the factory connector.  It is also the correct color for easier installation

6. Aftermarket Microphone for factory location (optional)

Your car has a factory location for the microphone used with the factory phone.  It is in the steering column.  That microphone cannot be used with an aftermarket radio This microphone gives you a clean look as well as good sound with most aftermarket radios. (see installation video below)

7. GPS Antenna Adapter (optional)

I usually remove the center channel speaker and put the antenna that came with the radio to the right of the speaker under the dash.  But this is also an option.

If your car had a factory GPS antenna you can reuse the factory antenna. If your radio requires a GPS antenna.  The antenna is located on the passengers side under the plastic cowl under the windshield wipers.  You will need 2 parts.  First the wire is an extension made specifically for your car to get from the antenna to the radio cavity. Then you will need a 2nd cable to convert that end into the end needed for your new radio.

8. SiriusXM Antenna Adapter (optional)

This is a rare option but I’ve seen it a few times.  If your car is equipped with factory Satellite radio we make a wire that allows you to reuse your factory antenna.  We have not made a satellite antenna retention cable cable specific for this car so were going to recommend you use the one we made for the Audi R8.  If you do use this please let us know how much sticks out of the dash. We have another one that is 78″ but we think its too short.

All SiriusXM ready radios require this external tuner in order to listen to SirusXM.

9. Backup Camera (optional)

This camera is designed to replace your factory license plate lights with aftermarket LED lights that hold a camera.  Out kit also includes a 2nd light without a camera so that your lights actually match.

10. Tools (optional)

Panel Pry tool set used to remove panels in your car.


Here are our choices for radios.
We currently recommend Sony because they have quality screen screen and are very easy to use. They also have a 3 year warranty (Except the 3200)
XAV-AX3200 is a budget radio
XAV-AX5600 is our wired Carplay/Android Auto recommendation because it has a nicer screen than the budget radio and doesn’t have a plastic border around the screen.
XAV-AX4000 is the budget wireless Carplay/Android Auto recommendation since it has the same screen as the 3200
XAV-AX6000 is the wireless Carplay/Android Auto recommendation and our overall favorite radio
