I'd like to replace the radio in my 2004 D2 HSE with an OEM unit (mostly because I don't want to go to the trouble of trying to install anything else and get it to work properly). I have the high-level Alpine unit with the 6-disc CD changer, but no aux input & no nav. I haven't pulled the head unit yet so can anyone out there tell me what the part number of the stock radio is? A Google search pulls up several model/part numbers variously labeled as anything from a 99 to 04 and everything in between, but don't say whether they're for the base level or high level.

I saw one that said it had aux input--would that one work in my D2, and if so, where would the aux jack be if it had been installed on the car at the factory? Not looking to put too much effort into this. Plug and play is preferred but running a couple wires from the back of the head unit to an add-on aux jack is (barely) within my electrical abilities. Does a replaced radio require "marrying" to the VIN?

 

If you found a stock head unit for sale with an auxiliary jack it was more than likely upgraded by a company that offered that service years and years ago. I don't think any DII radios came from the factory with an AUX jack.

But here's my question. Why bother with an auxiliary jack? Why not just add a Bluetooth adapter so you won't need to plug-in any wires and can play any audio from your phone?

Many of us use the unit from a company called GROM Audio. I've had one installed in my truck for probably 10 years now and it works great.

 

I don't know of any head unit that had an aux input, I know for some versions of the seven seaters I believe had either an aux input or a headphone jack, not sure which. The stock unit out of my base model is XQD000340PUY, or at least thats what mine looked like from a google search.

I don't believe they made different dashboards for the different head units (the ones with nav and whatever) but I could be wrong. Easiest OEM option for just adding an aux would be to get the base radio (XQD000340PUY) then get the GROM bluetooth/aux adapter for it. You basically unplug the CD changer from the back of the unit and plug in the GROM unit and depending on if you got the bluetooth or not, running a few wires. Pretty self explanatory.

Cheapest option would be get a $30 radio off amazon and the necessary plugs to adapt to it. If you aren't to savy at doing that, check out crutchfield.com and they'll tell you which units fit and they'll even splice all the adpaters for you so its just plug and play for the most part.



EDIT: just saw mln's post after I posted... Same idea, GROM is the way to go to keep it simple

 

Could very well be an upgrade. Yes, Bluetooth would be even better--I'll look into the GROM. A few months ago I found a web site that advertised replacement radios for several European vehicles including the Disco 2, and they had regular, aux and Bluetooth models, but when I revisited that site last month, they no longer stocked any of those. I have to replace the radio head unit first--volume **** doesn't do anything anymore. Volume control on the steering wheel still works but sometimes it confuses itself with the mode control and switches input instead of volume. Figure the radio is easier to fix/replace than the steering wheel control...

 

BTW, I assume hooking up the Bluetooth adapter would make the CD changer inop. Wonder if there's a way to splice it in to where both are operable. Both my Saab and Mercedes used the CD input for the Aux. In the Saab, pressing the CD button a second time switched to the Aux input; in the Mercedes, the Aux overrode the CD input when it was sending a signal. Not sure how those were wired, though.

 

That's correct. The GROM uses the CD changer input making it inop. Just put all your CD files on your phone!
