Hello all,

in Europe (and Australia) many Chrysler, Jeep, Dodge cars used to come with the RAR (or REG) radio. It is similar to the RES radios but it can swallow 6 CDs and has RDS. Unfortunately there is no AUX in :(

I so very much want at least an AUX in in my Jeep Compass 2008 (European) but where on earth do I find correct information about the interchangeability of these head units?

Here are images of a RAR / REG radio:




I have read Jeremy Schrags article about the RES radios and found that the rear connectors of the RAR radios are very similar (but upside down).

Of course, I just would like an AUX input but additional Bluetooth would also be great, so I'd like to replace the RAR unit with something that fits and has all these options, such as the REL unit.

Here are images of a REL radio:





Again the connectors on the back side are very similar, with the addition of a CD-changer.

Now the big, big question is: will it work? Can I simply replace the RAR unit with a REL unit? Will I damage something if I try it anyway? On the internet I cannot find any information about this, except from vendors who state that the connectors MUST match. However, they may be playing it safe to avoid complaints or litigation.

Thanks to anyone who can help!

Welcome to Allpar. I have only dealt with NAFTA radios and not European units. The Euro units have a security code that must be entered and may have other differences that I am honestly unfamiliar with. I don't want to steer you wrong.
I upgraded the radio in my '07 Caliber from an REF to an RAK with no problems. The Caliber and Compass are both PM body and similar over here. The Patriot MK body is also a similar architecture to the PM.
Reading through some Jeep threads, I found some answers that worked for others. Do you have a cell phone with aux or Bluetooth that you can use for streaming music over the Uconnect or Hands-free module? Is this system used where you are?
We do have some international members, maybe they might chime in if they are familiar with this?

I believe you will have issues with the radio portion. AM will likely not work due to a different freq separation between the US and Europe and fm will only get half the possible stations as the US only broadcasts/receives the odds (e.g. 88.9) where Europe will do both even and odd (e.g. 88.8 and 88.9)

Correct. I had forgotten that Europe is 9 kHz steps for AM and we are 10 kHz steps. FM in Europe is 100 kHz steps and we are odd numbered at 200 kHz steps.
Our FM pre-emphasis timing is different as well.
It would have to be a European radio. Older radios used to be configurable manually, but the newer ones use market-specific software burned into the microprocessor.

Thanks for your replies. I don't really care about listening to radio, especially not AM radio. But I will not take the risk as other things may also stop working I guess.

As for the Uconnect system, I have found this: 82210081 - Genuine Mopar HANDS FRE-CELLULAR PHONE (at https://www.moparpartsgiant.com/parts/mopar-hands-fre-cellular-phone~82210081.html )
Mopar parts number: 82210081

However non of the vendors mention the RAR radio model as a compatible radio or indeed the RAQ which is very similar. Also, I can not find if this module plays music through the radio, apart from the phone calls. Any ideas?

The real question is which radio is compatible with the vehicle and what media is compatible with the radio. 2008 PM/MK/JS would still be a fairly simple audio system compared to now.
Unless you can wire in an Auxiliary input to what you have, you may need a different radio. I am too unfamiliar with European security and compatibility requirements to advise you on this.
I see the 82210081 has been replaced by 82211879. If your phone or other 'discoverable' Bluetooth media device can stream music through Uconnect into the radio, is there a way to do this?
I agree that the connectors must match. I doubt that you would damage anything, it just simply won't operate. If no resources or suggestions show up here, is there any local vendor you can ask or Chrysler/Dodge/Jeep salvage yard radio upgrade available to you? If you do find a used radio, you need the unlocking code for it also.
I have used Metra to get radio connector pigtails and adapters for a Caliber and Caravan upgrades. I have no idea on compatibility with or between European systems.

Unfortunately, local Jeep dealerships know NOTHING about older Jeep models. They just say "you need the exact same radio" :) I am now trying to find a UK-based radio specialist, which is closest.
