How hard is it to install an aftermarket head unit ? Where do I connect the wires to my speaker ? I know there's a 20pin connecting to the factory radio, but how do I connect wires to my speakers ? I am connecting the Pioneer Navigation system to the In-dash LCD with the Pioneer Master Control unit. The problem now is that I don't know how to connect the speakers to the Master Control Unit. Please help.

Installing an aftermarket head unit is relatively easy. First thing is to snap off the dash trim panel around the radio. You can either carefully remove the fog light switch plate, stick your finger in this hole and pull to snap it off or, I have found it easier to wedge a couple of fingers in between the steering column and the panel and pull to snap it off. You will need to pick up a Honda wiring harness adapter when you purchase your new head unit. It allows you to simply plug the new unit into the existing Honda harness. See the photos of my installation here:

No the steering wheel controls will no longer work. However, if your new head unit has infrared remote control you can use Steering wheel controller PSIW3. See http://www.peripheral-aamp.com/periph_products/steering_interface.htm

If you want 4 more buttons (in addition to the 3 factory buttons) and are handy with electronic wiring/soldering you can add even more buttons by using the supplied resistor network. See my steering wheel photo in the Gallery.

Headunits are usually quite easy to install.
With wiring harnesses, installation kits (not really needed in this case), etc... its practically plug and play.

I'd say the tough thing is if you've never done this type of work before... Take a look at this PDF showing the Kelton Sub installation.... It has some pictures on how the center panel pops out and how the radio/pocket screws into the dash....

As dlh2 said, all you need to do is get a wiring harness, and mount the radio to the existing bracket/pocket assembly, plug it in, and put it back together. The beauty of the harness is that once you've spliced together the radio wires with the harness (outside the car), all connections are made with one connector.

The biggest caveat I would say is watch out on the radio mounting for the little side clips Honda uses to to mount the pocket firmly to the radio..... Honda has designed the radio to meet DIN standards, so mounting the radio to the side brackets is a no brainer with screws. However, the pocket (Honda does this for all its cars) attaches with these little clips to slots on the radio chassis. (see pic on 4th row, 4th col in dlh2's fototime gallery....) I've read in this forum that people have had success with just the side force of the brackets and friction to hold the pocket in place. In every install I've done in a Honda, I've always used a dremel tool tool to make slots in the aftermarket radio's metal sleeve (not chassis!!!!) so that I can rigidly mount the pocket to the radio. This works great, and takes very little time if you have a dremel with cut-off wheel attachment...

In as far as wiring the radio wires to the harness, most people use insulated crimp connectors. I usually use solder and heat shrink tubing, as it is the most reliable, but this type of work is not really necessary for a basic install....

One last thing, if you feel uncomfortable hunting around for a harness, etc... Crutchfield will sell you a radio and include free a harness, and technical support to make sure your install goes well. You can save some bucks though going elsewhere, and Crutchfield does not carry brands that some might consider "higher end" such as Alpine, Eclipse, Nakamichi, McIntosh, etc....

Good Luck,
SJ

Here is a recent install of the Pioneer DVD NAV in a S-Class we did.

For the harness,
Search under 1721 at http://store.autotoys.com

Search under 828 for the kit

We have at least 3 dozen of each product in stock.

For the DVD NAV install, look here
http://www.autotoys.com/New_Tech/DIY_2000/S-Class_Navigation_AVICDVD/s-class_navigation_avicdvd.htm

We have an install of a Pioneer 7300DVD with the AVIC 9DVD and AVMP8000R available, but it has not been uploaded yet to the tech section.

With the dash kit and wire harness, it will be plug and play.
