Head Unit connections for ASK amp

[David Falconer]

Hi, I have the Sound Plus package in my 987 Gen1. The old CDR 24 system is a bit knackered so looking to upgrade Head Unit to Kenwood or Pioneer double din with Carplay. I obviously need some kind of harness to connect up but looking online there seems to be conflicting details of whether this needs the full MOST harness (connects 2 £150) or a simpler cheaper one (?).

 

The car is a Dec 2005, so would have been one if the earliest.

 

Added photo below of the Amp itself. I don’t really want to replace all the speakers, the sound will do. However if the full £150 harness is required wondering if replacing Amp will make things simpler. Next question would be which amp would work with the stock speakers.

Hi David, I'm much in the same boat Gen 1 S . I've been looking around but I cant answer your specific questions. However my car has Bose which have fibreoptics in them somewhere that requires a FO connector to the head unit. These FO connectors are £150. I've looked at a local specialist who quoted anything from £800+ Vat to 1200+Vat which is a bit rich for me as I'm pretty tone deaf!

I'm toying with my local Halfords who are quoting about £650 total for pretty much the same exercise. I want better Sat Nav and hands free. I have some feed back on this forum recently via e-mail from someone who  was quite happy with the Halfords  instal.. Halford also., just from Monday, vastly increased the range of units they can offer. whether that's just  my local branch I don't know

Yeah, think the BOSE set up is a lot more complex. I’ve just gone ahead and ordered a head unit, DAB aerial, fascia/cage, usb thing to stick somewhere and a cheap iso harness that I may or may not need. 

 

Found stuff about power feed being required but will try to figure it out as I go along. 

 

My CDR 24 is knackered so nothing to lose.

I installed this beginning of this year, it’s compatible with CD-R 24 and Bose as it comes with a MOST adapter and all wiring looms to suit. It’s just plug and play, sat nav is spot on as is Bluetooth tele prep etc and the facia matches original silver or black finish. The only problem is its price, at £899 it’s not cheap :(

I had a look at the Dynavin and it's a great looking bit of kit that has a nice OEM look about it. However it’s £900 plus another £290 for an Apple Carplay module. I could upgrade the entire sound system for that kind of money.

 

I would only ever use Bluetooth streaming, carplay for Waze and DAB, meaning all the extras on Dynavin like DVD, SD Card, HDD, Nav, TV would just be wasted.

You will need the Connect2 cable for aftermarket HU if you are wanting to keep the reversing sensor noise and steering wheel controls. Also, the crossover for tweeters is built-in to the amp. On my Gen1 with basic sound package  it still uses fibre, so I would assume it would have the same on your car. Another thing to take in to account is the HU power rating for the speakers (i.e. watts and ohms), not too powerful or under powered. Oh you will also need a powered phantom feed for the aerial.

 

In my case I switched over to Pioneer HU with Android Auto, used the Connects2 cable (2nd hand on Ebay). Later changing the speakers to Infinity Kappa components, and lastly adding a Hertz amplifier.

Useful, thanks. I’ve already ordered Pioneer HU with Carplay (DA230DAB) and the fakes aerial connector with phantom power. 

 

I’ve no steering wheel controls, other than for the Tiptronic but do have reverse parking sensors. Have a feeling i’ll Have to bite the bullet and get the pricey Connects 2 cable.

Fair enough, sounds like you are sorted now. I retro-fitted the multi function steering wheel buttons, works well and I use all of the time

 

For people looking for a HU with similar requirements - 

£459 + 15% discount at the moment. Not used myself, but another option for people to consider.

The OEM look and very simple install was the reason I went for the Dynavin, yes it’s not cheap and if your pretty switched on and tech savvy then you could as you said upgrade your entire system for the same cost etc.

Finally got the install done and it took a lot of swearing...

 

The problem is the Connects2 PO51 harness is mainly Plug and Play with everything fitting together as it should but they have ignored a switched feed on the cars power block - thin red/black wire. This need connected into the switched feed (red wire) going into the Most Interface. Took ages to figure that out, but no need for extra power from fuse box or anything like that.

 

Apart from that other gotchas are the A pillar is length of car and full of clips that break for DAB Aerial. All goes back much easier than it comes out though. The painted interior plastic is easy to mark, need to be really careful. The Fascia also needs a couple of extra screws In the sides to hold in place at the bottom.

 

Anyway all done and working now, pic of wire for reference and final install.

Glad to hear you’re all sorted now @David Falconer, looks a nice tidy install
