Help please! Upgrading 2007 JGC with Nav to Pioneer SPH DA120

I wonder if anyone on here can help me please as I'm struggling to make head nor tail of the info I've found on the Internet.

I bought the Pioneer SPH DA120 from Halfords who recommended an aerial adapter (needed an extra part), harness and facia.

I mentioned that the car has an amp but they said it would be fine, just plug it in and should work. They also said the blue/white lead from stereo can be left as is an that yellow and red from stereo can be switched if necessary.

I tried plugging it all in after installing GPS and microphone and stereo works when ignition is on (not when just turned to ACC) but no sound from speakers, just a clicking sound, which I assume is from speakers and that continues even after turning off ignition and removing key!

The harness ordered by Halfords is pretty basic and from what I can see provides connections two yellow wires, two black, a blue, a red, an orange, an unconnected brown (?), and the 8 speaker cables.

The Blue/white from stereo aligns with the blue in the existing car ISO connector. The yellows align, the red aligns, the blacks align, the orange from stereo (illumination) did not align with the orange in car ISO but instead aligned with an orange/white wire (not sure what this is), but I switched it.

There are a number of other wires in the car ISO that don't align to anything with the Halfords harness/stereo. I assume they are for steering controls etc.

So my question is, if the speakers are powered by the amp, then if the new Pioneer stereo sends an amplified signal down these wires to the amp, how does the amp handle this signal and what is powering the amp?

Should the amp be bypassed? If so I assume I'd need to join 8 new cables from where they join the amp up to the head unit (and disconnect the amp) or just disconnect the speaker cables from the amp and splice/connect them to the speaker cables running from the amp up to head unit?

Perhaps I'm missing a lot here but have little faith in taking it to Halfords!!

Any help greatly appreciated.

Thanks for the above. I have the Nav (REC or REJ I think it's called) with Boston Acoustics in my 2007 JGC Overland and now having taken a bit of a look beneath the steering wheel there is a right mess of wires there. There is also a separate microphone (perhaps Parrot), so I think someone has had an aftermarket in there. There is a fair bit of splicing (hand twisted together with insulation tape) random wires terminating in connection blocks etc!!! I think the owner had been doing all this to pick up some constant and ACC from the ignition, but a right mess to tidy up!

But what I can see is an additional harness with a small black box in series with speaker cables attached (not other power/earth etc), this attached to the car's original 22 pin grey ISO connector and the resultant ISO connector on harness was plugged into the original NAV stereo which still works as I tested yesterday.

Interestingly the grey original car ISO connector with 22 pins also makes the original NAV stereo work fine. This appears to just have two power wires in position 1 and 12 (both red and orange I think) and then all the speaker cables (although they may perform other functions).

So my question is, when you did you upgrade, did you just attach your new harness to the original grey 22 pin ISO connector and then attach other end to stereo? My thoughts are that there would be a lot of unused wires from the Pioneer stereo that aren't hooked up? Eg orange illumination, blue/blue white, red.

Any thoughts?

Cheers

Yes i plugged the CHTO-01 harness into the factory harness and wired to the
CHTO-01 from the Pioneer Headunit. Just following the directions as I went. Also hooked up ASWC-1 to CHTO-01 for steering wheel controls.

Re: Help please! Upgrading 2007 JGC with Nav to Pioneer SPH DA120

OK, so the pain continues!!

I couldn't get a CHTO-01 and ASWC-1 without it being shipped from US on ebay and very expensive, so I contacted Connects2 (Connects2 Ltd) and they informed me that the correct harness was the CTSCH00C (link) and that I also needed the compatible Pioneer Lead, both of which I purchased from eBay for a total of 89.90.

Happy days you would think...

Well, I plugged it all in as per the very limited instructions (available at the link above) and did not connect up the blue/white wire from the head unit to the blue/white on the harness (as I understand the amp in my Jeep GC CRD Overland with NAV 2007 isn't powered on that way) and didn't connect up the reverse (purple) or speed (pink) as they are not applicable to me, but I did connect up the green (park) wire to ground (as suggested by Halfords!!!). I plugged in the connector to the OEM grey 22 pin connector and...

No sound from speakers at all but stereo working fine and even able to make phone calls where they can hear me but I can't hear them!!

So I tried connecting up the blue/white wires from head unit and harness and hurray, sound from the dash speakers but nothing from the 4 door speakers. These speakers do work as I tested the OEM NAV stereo again to check.

So I contacted Connect2 again today and they helpfully said:

I'm afraid is sounds like your vehicles platform has got more than one amp in or a diffeent can bus data platform or both. We might not be switching them all on because your oem system was a navi platform and our adaptors will not be fully compatible with the data on a navi platform system's. Sorry for any inconvenience this may have caused.
and

I'm afraid there is no work around's because the data on your vehicles platform will be different to the none sat-nav systems that our adaptor are designed for.

Your model and year is correct but your oem system is the wrong data platform i'm afraid.

I may be worth speaking to a local audio dealer to see if they know of a work around to bypass the can-bus to switch the other speakers on in the vehicle.
Please be aware of this company in future as they may give you crap advice!!

So, any bright knowledgeable people out there that may know a work around for this please?

I don't understand how the amp is powered on from the OEM grey connector behind the head unit. Do you?

Halfords said they would take a look tomorrow as they have already sold me the wrong leads!! But I have little faith in them too.

What is a CanBUS and is that even involved in turning on the amp?

PLEASE help before I go crazy!!

Re: Help please! Upgrading 2007 JGC with Nav to Pioneer SPH DA120

Ok a further update on the saga!!

Halfords added an ignition (ACC) lead that they connected directly to the red lead from the head unit and now the door speakers are working, but no sound still when phone calls are made and when fading front to rear from settings in stereo it is reversed!! However when I unplugged the new lead (out of curiosity) all the speakers still work, so I'm not sure what the hell they did, perhaps just fixed a loose connection or gave the amp a kick start.

So now I am wondering whether it is an issue with either the firmware in the iPhone or stereo.

Really just about had enough now as I only wanted a stereo that gave hands free option but now have a rather expensive radio!!

Any suggestions anyone? PLEASE!!!

Re: Help please! Upgrading 2007 JGC with Nav to Pioneer SPH DA120

Ok finally PROBLEM SOLVED!!!!!

For those that might have a similar problem when using the harness I purchased above, I plugged in the blue/white wire from stereo to harness, I grounded the park wire, Halfords added a new red ACC wire that connected directly to the red wire coming out of the stereo (not the one on the harness). But crucially to get the sound from speakers when making/receiving calls I had to reverse all the speaker wire pins in the 22 pin connector on the harness (I.e the one that plugs into the OEM 22 pin connector.

Front left negative was switched with rear left negative. Front left positive was switched with rear left positive. This was repeated for all eight wires.

Finally, I tested it and amp is still powering on, sound from all speakers, and when calling I can hear people Hooray!!!

The problem was that the amp in this Boston Acoustic set up receives it's sound from rear left and right output from the stereo and just amplifies this back to all the speakers. This is fine for normal audio but the sound for voice calls is output from the stereo via front left and right, so the amp wasn't receiving the voicemail sound to amplify it.

My fix was simple but works and I hope this post will help someone else solve this problem

Any help greatly appreciated.

The WK or WH grand cherokee uses a canbus data network. This will need to be converted into analogue signals in order for it to properly work.

These are available from PAC, Scosche and a few others. I have just posted video of an install using a Scosche adapter interface.


Regards,

Paul.
