Title: Radio Upgrade
Post by: stevegreen0 on April 20, 2006, 01:15:46 PM

Hi All

I have a 98 Grand Cherokee with the Infinity Gold Radio/Cassette Player but without the optional CD Changer. I was thinking of getting a secondhand Changer and connecting it up but is there a standard Radio/CD Head Unit (possibly from a later model) that will fit in the dash and connect straight up to the existing wiring connectors?

Cheers.

Steve

Have a look on ebay.com (not uk) for mopar/chrysler/jeep radio. You should find loads of OEM units for sale. Be careful though, the yanks use 10kHz steps for AM radio and we use 9kHz, so you're not gonna pick up much in the UK with a US radio.

You could go down your local boy racer shop and see if audioleads to a fascia adapter and wiring harness to put in a standard stereo.

There's usually a few knocking around on ebay UK to.

I have a stock head unit from a 98 XJ in the cupboard if they are the same as fitted in the grands.

Cus I'm bored, I've looked and you need an autoleads FP-02-00 fascia adapter and a PC9-407 harness adapter if you have a seperate amp.
The fascia adapter for the 98 XJ is the same one but the harness is different if it has an amp. You could use it, but you'd need to re-wire half the car to bypass the amp.

The Mopar changer is ok. You need the 6 disc version, and it needs to come with the correct cable, which has a round DIN plug at both ends. Later ones don't work.

Forgot to mention.  The head unit I have is out of a Limited with the Infinity system.

Oh,......................and another thing.

The Infinity system is an amp and speaker upgrade.  The head units are the same.

The XJ must have high and low level outputs to use the same head unit with and without external amp.
My WJ unit has just one set of outputs - if theyre high level, it would explain why such a supposedly expensive stereo sounds like a 30 quid piece of crap.

As far as I'm aware, on XJs ZJs and GS Voyagers, they all have the same head unit with it's own internal amp. The Infinity amp, if fitted, then acts as a booster amp. The same applies to later stuff like KJs and RG Voyagers and stuff, but some have powered speakers instead of a single amp.
