hmm.. if it is defective, then they should offer a replacement without any penalty.
Do you get the other functions from the CanBus box => reverse, parking brake etc?
If you get none of the functions, then it might be a defective unit.
Or.. you are yet to discover some blunder in the installation (I've done that before
)
The only "secret" that the Connects2 told me after I opened a support ticket was that when you open up the CanBus box, there are dipswitches to set if it's a Sony HU.
For everything else, you can leave them as they are.
It's a bit disappointing that they don't have a microUSB or other port that you can run diagnostics on via some test app or so.
I really liked the minimalist design of the alpine, but sadly I'm an android-person.. so couldn't give that up.
And the one issue that I had with that alpine HU was that CarPlay is the only thing you can ever do => no BT, no Aux, no USB media.

The IXL-107 Alpine unit with carplay does have BT, and USB media. Works great.

Wow I need to spend some time really reading through this. I’m about to dive into this for my 997.1 Targa 4S...
Someone mentioned this unit from Crutchfield:
https://www.crutchfield.com/p_120PO9...Interface.html
has anyone used this successfully? It’s half the price of the nav-tv unit, and being from Crutchfield I’m a little more inclined to trust it more than the Chinese knock-offs on Ali-express.

I just had a local installer do this (also doing a backup cam so getting paid help was worth it) and I am pleased overall so far (ilx-107 with wireless carplay is awesome) but it’s going back in to get the parking brake connection done up properly to access advanced settings.
I read somewhere that you can actually split out the bose subwoofer and tie it directly to the head units subwoofer line. I suppose this would give you “.1” control over that, but wondering if anyone has done it and whether It’s worth it?

I am in the process of doing this for my Cayman. I plan on running the two RCAs for the HU and one for the subwoofer through a noise isolator for ground loops, then feed the single RCA to the sub alone.
Not sure if I need to disconnect the Bose optical from the sub, or not. On another thread, it was pointed out that the Bose optical is a ring topology, so you need an optical repeater to not break the loop if you disconnect an item.
Also, FWIW, I have one of these Longate MOST adapters spare from my build. new, never installed. Vendor said I would have to send it back to china and they would only give me a portion of the cost back. $80 shipped CONUS if anyone wants to try one for a 20% savings.

Read over this thread and I'm still not clear on the viability of the Seicane MOST adapter.
In my case it's an 08' with Bose and without steering wheel controls.
--And here is a current link to a unit that's available and still reasonably priced (most of the other links were dead): https://www.aliexpress.com/item/Seic...846889436.html--
With this unit, I'd lose fader control front to rear? I never change this so as long as its set properly before removing the stock head unit I'll be ok?
My sound quality will not go down?
Is there a gen 2 of this unit in which the fader issue fixed?
Is there anything this unit won't do that others will?
Thanks for any help. Thinking about going to a Pioneer AVH W4400NEX.
I want wireless carplay and XM radio which apparently has very limited options at this point. Would prefer a volume **** but can't get that with the other two.

Even the NAV-TV module ($650 or so) does not support fader control - you'd need an adapter that can send fader info in MOST protocol for that.
There is a russian module someone mentioned in the forums that might do so - $250 or so, but noone has verified it works so far.
So long as you split R and L channels to pickup F and R, you would at least have fader and balance blended into one setup
If you don't expect audiophile quality, then you would be much happier with any of the MOST kits out there.
If you are really particular, then you should rip out the entire system and choose the exact setup you want. Some folks have done it and there are threads with a lot of details.
Thanks

Question on CanBus and Seicane
The bottom end would be the Seicane - 70-129 - depending on where you find it. Simple install - Keeps Bose - you lose the CanBus
Next is the Axxess (can find it at Crutchfield) - 300-400 range - can keep CanBus - loses fader
Next is NavTV - as high as $650 - Same as the Axxess - but was first - so most people are familiar with it -
I went with the Seicane - I have an 06 C2S - works fine - I just don't get the radio read out on the Spedo cluster - (not worth 200-400 more to get that and STILL lose the fader).

I have a question on your comparison above, I don't know pretty much what does the CanBus does or is for and what I would loose if use the Seicane. Does loosing the CanBus will affect any function on the car or OBDII functions?.
Thank you in advance for your help, if I move forward I will bother you a lot..hehe

A member on the Cayenne 955 forum had another workaround for the F/R fader issue. He essentially "half-ditched" the MOST/Bose system. He did the following:
1) Kept the MOST (connected to the front RCAs on the headunit) adapter for the front channels
2) Used the rear RCA outs on the headunit to feed a small amp that was then wired to conventionally drive the rear speakers [and sub?].
That may be interesting to some.

FYI, for what it's worth, I used the official NAV TV unit ($$$) and ended up with some high frequency hiss / alternator whine that just wouldn't go away. I added ferrite bead filters on the power and ground wires and the noise went away. Just as a tip for anyone who's getting line noise. In fact, I have some leftover if anyone wants some (just pay shipping).

i have had Z E R O issues with this
I don't get the display on the dash for the radio station - little things that don't matter.
I went with the Pioneer 4400W --- it's wireless/wired Carplay and I AB SO LUTE LY love it -
I am trying to find all of the piece to do this in the V10 R8 - I can't live without CarPlay!!!
The Porsche was SUPER easy - BUT - DO NOT test fit the unit - you'll end up by taking 1/2 the front dash apart to get it back out - It says that in the manual.

I am replacing both the HU and Bose AMP in my 997.1S What I can't tell is what harnesses should be used. Some were listed in older threads but those EBay auctions or part numbers are no longer valid.
Looking for:
1. Harness to connect Sony HU to factory wiring. (HU to AMP is a no brainer).
2. Harness to connect aftermarket AMP to factory speaker wiring.
Please let me know what you used and if it required modification or was plug-n-play.
TIA Brian

Honestly the official unit works fine, but it is definitely WAY over priced. When asked about whether there should always a subtle hiss when the unit is on but not playing they said yes that’s normal. And there’s no fader or direct subwoofer control. For a $100 adapter I’d be ok with those compromises, but for a $600 part that’s been specifically engineered for my car I’d expect more polish.
edit: I understand the Bose unit is strange (I’m pretty sure it’s doing Dolby style surround sound processing with the center and rear channels) but you’d still think this could be adapted correctly.

I just installed a Kenwood HU and used the Crutchfield wire harness and the Axxess MOST adaptor (350). The pre-done wire harness makes it much easier to install. I have no hiss at all. I dont believe that is "normal" other than it being normal that they prob dont want to do any more work on it!The only thing i cant get working is the volume click wheel on the steering wheel. All the other button work except for vol which is the only one i really wanted. And btw i cut all the lock tabs off the face plate mount. Its not going anywhere and will be relatively easy to remove if need be.
I dont think the sound is as good as the oem unit. You are going from a 4.1 system to a 2 channel system. I need to play around with the EQ more but there seems to be a disproportionate amount of volume out of the 3 speakers in the dash ie the 2 tweeters and the centre channel. The 2 front door speaker (ie the 4" and 8" driver i believe) are much lower in vol than they were before. Is it possible to just cut the centre channel? Would that effect anything else?
If anyone has a recommendation for a proper tuning, would love to hear it
Cheers
