XM problem...

When properly installed, the quality of an fm modulated XM system is very good.  It's not quite CD quality but certainly better than tape and typical fm radio.  The term fm modulated kinda makes it sound like it's gonna be a radio broadcast kind of thing, but the antenna cables plug directly in to the monitor, so it is still a direct connection--and it certainly sounds like a direct connection.  This also means it is vary rarely susceptible to interference.

Only problem is that to listen to standard fm radio you have to turn the modulator off, but that's as simple as pressing the power button on the xm display.  Once you've done that the fm radio reception will start to function normally again.

For those like yourself that want to keep their factory systems intact, the fm modulator is a great way to go.  with most factory equipment, even the premium systems, the difference in sound quality is minimum at most.

Also remember that for those who are in to the new SkyFi unit from Delpi, the only way to hook it up is to use a modulator or tape adapter.

Just out of curiosity, what year is your vehicle?  Most likely you can upgrade to an aftermarket head unit and keep the use of the steering wheel controls using an adapter like this one, although I am unaware of a way to use the stock cd changer with an aftermarket deck.

hello,

  I am an installer and I know for most aftermarket decks you may be able to retain your cd changer.  There is a company called periphial and they make excellent components for such.  They are just adapter plugs the are for Alpine/chrysler, Pioneer/ Chrysler, Clarion/Chrysler, etc.  They also make the interface to retain your steering wheel controls.  Check with you local car audio shop and they should be able to get you their information.

They sell cd changers that can be used as direct replacements for factory models, and that need no converter or adapter to connect to a factory system.  Essentially they're just like the OEM part you'd get from a dealer, but instead of being 600 bucks and saying "Jeep" or "mopar" on it, it's only 200 or 300 bucks and will say something else on it.  Works and sounds the same.

Also, using an adapter from PAC, blitzsafe, P.I.E., etc., you can use a factory head unit that has cd changer controls, to directly control an aftermarket cd changer.

You cannot, however, get an adapter that lets you use an aftermarket head unit with a factory cd changer.  The only exception to this was a few months ago I came across a site that talked about how the factory changers in some mid-nineties european cars were made for the manufacturers by companies like alpine and pioneer, and happened to be compatible with certain aftermarket  head units from the same company, because they used the same type of plugs and the same data protocol.  I don't even remember specifically which vehicles they were but I do know for a fact that you can't do that with your jeep changer.

I still think your best bet is to get a head unit and its optional auxilliary input adapter, and use a y cable for a direct hookup from the delphi unit to the head unit.  This way you bypass the modulator altogether.  This is the same way that it's hooked up to a home stereo when you use the home kit.
