987 Double DIN Installation (upgrade) NebulaOdyssey on BoXa.net BoXa profile Performed on 2006 987 Boxster with Sound Package Plus (SSP) (Gen 1 or 987.1) NB: Will also work for non SPP but not suitable for Bose systems Tools: 3/16” Allen Key (Hex)Torx T-25Torx T-20Wire Strippers (with crimper)Soldering Iron (with some solder)Very small flat blade screwdriverPhillips and Flat Head screwdrivers Equipment: Double DIN radio unit of your choiceAn ISO DIN wiring harness adapter (if your radio unit didn’t come with one, mine did)Double DIN fascia and cage kit, like CT23PO03Fakra aerial adapter, if new unit requires ISO then a PC5-100Wire (for +12V ignition, <6Amp should be fine @ 12V), 2-3 meters (I bought 10m)1 Spade Crimp Connector (a Blue sized one)1 Inline fuse holder (<6Amp rating again should be fine @ 12V)5Amp Time Delay (slow blow), inline type of courseElectrical tapeSteps: First you will need to remove the old terrible CDR24 unit out of the car. I used this very good guide http://www.planet-9....removal-29.html Next you want to get all the wires prepared ready for the car. This step does involve soldering, so take all the precautionary measures required to prevent yourself or others from getting injured and make sure you work in a well ventilated area. With the SPP you will have an ASK amplifier in the front that needs an ignition on signal, as will the new radio unit. If you do not have SPP your new radio will still need an ignition on signal, but you won’t need to move the pin in the ISO harness. The following is performed on the harness adapter not the car’s harness. Remove Pin 4 from the ISO adapter (red wire) by inserting a small flat blade screwdriver and pushing on the tab that holds the pin in place whilst gently pulling on the red wire. Your red wire may have bullet connectors, if so disconnect them as it makes the next steps easier, if not then it doesn’t matter. Measure, by dry fitting, your ignition on wire from your radio bay around the drivers foot well to the fuse box (leave some extra as you can tuck it away). Strip some wire and solder one end to the removed ISO adapter Pin (red wire Pin). Once done use some electrical tape to secure the base of the wires together. On the other end strip and solder one half of the fuse holder (the smaller half). Cut another short length of wire and strip both ends, then solder the other half of the fuse holder to one end (larger half) and crimp the spade connector to the other end. Now you need to put the Pin back into the ISO harness, make sure you put this in to Pin slot 2, which equates to the ASK remote on slot on the car. You can put it back into Pin slot 4 if you have no SPP. If you have the bullet connectors, you can now connect them back up, yellow arrows. The speaker wires are all okay as they are, so no changes required. Check to make sure your new Double DIN radio provides either an aerial out or remote out to Pin slot 5 on the ISO harness, if not move your radio’s aerial power out to Pin slot 5. This is the power on, needed for the car’s powered antenna. Now route the ignition on wire around the driver’s foot well to the fuse box from the back of the centre console radio bay. Next get all the other ancillary wires into place. This includes any media wires for iPod/iPhone, USB and AUX Jack and the GPS unit. I think the best place for the GPS module is under the black plastic at the base of the window wipers. Open your front boot and remove the battery cover. Now push your GPS wire through the rubber grommet just to the left of the battery, it has an X cut in it. You only need to push a few inches few at first. The red arrow shows the grommet and the orange shows where I placed the GPS module. Stick you GPS module into place. Clean the area with alcohol and use a double sided sticky pad. Now climb into the driver’s foot well and take a look up towards the windscreen near the centre of the console where you might expect the grommet to be (front firewall). Grab the wire and have someone else feed more through as your route it down into the foot well (with one person you can push pull push pull etc...). Route the wire under the carpet and up into the back of the centre console to the radio bay. There are two Velcro tabs holding the carpet in place, simply remove and stick back. Whilst here tuck in your ignition cable up to the fuse box. Fit your aerial adapter to the car’s Fakra connector. Route your media/iPod/iPhone cables to the glovebox (or elsewhere, see end). To remove the glovebox in order to install these wires see my How To – Remove 987 Glovebox write up. The last thing is to install the mic. Install this where you like, I chose to have it above the rear view mirror, the wire is routed down the driver’s side pillar. All wires should now be routed. The following picture shows all the existing connectors on the car for information and installation purposes. Tidy up the ignition wire at the fuse box. Remove the fuse box cover and the three screws holding the box in place. The carpet and box should simply pull off (careful near the bottom), you may need to take out your floor mat. Route your ignition wire. Hopefully the small half of your inline fuse holder (from harness) fits through the bottom right slot in the fuse box; push it through from the back. Insert the spade into a vacant fuse slot that would be switched with minimum 5Amp (check your fuse map on the piece of paper on the back of the fuse cover). You can see the one I used. It needs to be the bottom pin of the fuse slot. If the fuse holder doesn’t fit you’ll have to route the spade through the fuse box slot and have the holder behind the carpet. Next, fit the cage that came with the CT23PO03 fascia kit. Test fit your radio to see how well it fits and to check the wiring is all okay. The foam pads with the fascia kit are pretty poor at holding the cage in a vertical position; however put one on the top and one on the bottom of the cage, although it should be very tight horizontally. Use a sturdy flat blade screwdriver to push out some of the side prongs of the cage to stop it being pulled out and use two at the top and bottom to act as ‘feet’ to hold the cage vertically in place. Make sure these will not foul the clips on the fascia plate. Test fit the fascia with the radio to make sure it’s all centrally aligned and pad up the bottom of the cage a little to centre the radio in relation to the fascia. This took one or two attempts. I also found that by giving the cage ‘feet’ it and made it more solid and also held the fascia in place better. Make sure everything is working as it should, then re-install the side panels to the centre console as well as the back panel pieces.
