There were a couple things I wanted on the replacement stereo: black face and red backlighting to match the rest of the dash and a front auxiliary input for easy and cheap iPod integration. The Kenwood KDC-MP208 matched this pretty good and the price was hard to pass up, $59 shipped from one of the third party sellers at Amazon. If you are hooking an iPod up to an auxiliary input I highly suggest a cable that gives you a line level output like this Cables To Go - 4ft iPod Dock Connector to 3.5mm Cable.

Type-S Owners: If you own a Type-S with the premium stereo (no pocket, like this) you will need to get a replacement dash kit to accept either a single or double DIN aftermarket stereo. This Scosche installation kit allows for either single or double DIN and comes with the pocket if you go with a single DIN unit.

Installing Double DIN unit: If you want to install a double DIN unit then you'll need the Ssosche kit linked above.

Head Unit: This JVC unit looks interesting as it has built in HD radio and customizable colors: JVC KD-HDR50. These units look like good matches to the RSX's red/orange backlighting too: Kenwood KDC-MP142, Sony CDXGT430U, and Sony CDX-GT330. I got the Kenwood KDC-MP208 but it is no longer available at Amazon. You can keep an eye out for it at eBay.

Installation Steps

1. Pull off bottom plastic dash cover that houses the power adapter plug. There are little tabs on the side to get a screwdriver in. Pop one side out and firmly work the rest of it out. It might be tough at the end, just give it a good tug straight out and it will give.
2. Unplug power adapter to get it out of the way
3. Using a small ratcheting wrench with 8mm socket or stubby Philips screwdriver, unscrew the two screws going up towards the stereo. They're at a funky angle and there's not a whole lot of room to work. Might be a good job for someone with smaller hands. I loosened the screws and backed them out by hand to avoid the risk of dropping them into the bowels of the dash.
4. Once the screws are out the whole stereo and hazards section will slide out with a little force. Grab the back of the stereo mount through the dash and give it a real good pull. Mine had never been removed and it took some pretty good yanking to get it to budge. I used a screwdriver to pop a clip on the top right corner above the hazards switch. Slide it out a few inches and disconnect the hazards wiring harness and then the stereo's harness.
5. Unscrew the stock stereo from the bracket and replace it with the new unit. Plug it in with your prepared wiring harness and test to make sure everything is working. Pan to each of the channels to verify the speakers are connected correctly.
6. Plug the hazards harness back in or your turn signals won't work. Wonder how I know that?
7. Slide the whole thing back into the dash while trying to keep all the new wires on top of the stereo so they don't get smashed behind it
8. Replace the 2 screws and pop the dash cover back on. That's it.

I'm really happy with the results. The sound on the inexpensive Kenwood unit is much better than the stock stereo. The bottom end was very lacking before, but now it is more than adequate with the stock speakers. Radio reception is good and overall this is a nice cheap way to get your MP3 player hooked up in an RSX.

Dash Kit Info: I got the Scosche TA2052B Single Din from Amazon, there's also a double DIN version.

Head Unit Info: I got a Pioneer DEH-P4800MP, but it is discontinued now which is too bad since the finish matches the dash kit almost exactly. I keep looking, but haven't found anything with as good of a color match. Try watching eBay for the DEH-P4800MP.

If you want to buy new, these Pioneer units have a bit of the lighter silver color and have received good reviews: Pioneer DEH-P5000UB , Pioneer DEHP4100UB, Pioneer DEH2100IB.

This is the stock stereo I had to work with. The trend has been towards completely integrating the stereo into a car's dash, it looks great but as soon as you want to install an aftermarket stereo in you might be stuck. The aftermarket dash kit is color matched to the silver around the vents.

Step 1 - Rip out climate control, unbolt and remove dash and stereo, unhook everything.

Step 2 - Wire up the wire harness so you don't have to cut any of the factory wiring.

Step 3 - Hookup stereo and test to make sure everything works before putting the whole thing back together.

Step 4 - I've got everything in and just need to stick the climate control panel back on. Getting the head unit and hazards/clock panel into the replacement dash was the most time consuming part of the whole project. First I couldn't get the hazards panel out of the stock dash but managed to pry it out after an hour. Secondly, the installation instructions for the dash kit were pretty brief, I guess you can consider a diagram and a few unintelligible sentences instructions. At this point I had also drilled a hole in the back of the pocket to feed the cable for the auxiliary input through.

Finish - With everything put back together I actually like the look of the replacement dash kit more than the original bumpy texture.

Audio quality is much better after a little EQ'ing and I can now hook up an Mp3 player. New speakers would be a nice upgrade, but the new head unit really helps the stock speakers come alive.

Not a terribly difficult project and I'm glad I did it myself instead of paying an installer a good chunk of change to do it. I probably got lucky since most dashes aren't this accessible and easy to work with.

I wouldn't even consider an FM transmitter and would only resort to tape at last resort.

The best option is to plug directly into your car's head unit through an auxiliary input. Even with stock car stereos there is a chance an adapter is available. And if not, I'd try a FM modulator (different from transmitters, they plug directly into antennae on the stereo to minimize interference).

I use to have a Kenwood head unit in my old truck and I got the adapter that plugs into the cd changer port and it worked great. Just ran the RCA cable out from under the dash and up to the center console and plugged straight in.

The best list of available adapters I've found is at Installer.com.

So in summary:

• FM transmitters (the cheap toys you get at Radio Shack) - avoid like the plague.
• Tape Adapters - Final resort if you are strapped for cash and you actually have a tape player (which is becoming quite rare on newer cars and head units).
• FM modulator - plugs directly inline with your car's antennae, final resort if you value sound quality.
• Auxiliary input - Stereo manufacturers are finally catching on and Aux inputs are becoming more widespread. They offer the least amount of sound quality loss and depending on your setup can be pretty affordable.

I think a lot of people view hooking up their Mp3 player the same as the headphones they use, they simply see no reason to upgrade. After dropping $200-300 on a very capable Mp3 player, most people will not spend the extra money to upgrade their headphones. This is why you see the trendy Ipod masses on college campuses walking around with their white earbuds stuffed in their ears. Spend another $35 on something like these Sennheiser PX 100's and increase the quality of your music, unless looking trendy and "cool" matters more.

The same goes with hooking your Mp3 player up in the car, don't spend $15 on the FM crap emitter, invest a little more and get a higher quality signal with less hassle. I look at it this way, how much is it worth to not have to listen to crappy radio music and commercials? Stick it to the man and hook your mp3 player up to your car stereo.
