2015 Golf TDI S radio upgrade to Navigation

[MattRabbit]

Where did you get all the pieces to do this upgrade? I’d really like to do it myself. I see so many things online actual radios at Allied then Apple CarPlay mirroring I’d really appreciate it.

I bought the head unit and screen on ebay and the USB port/harness from aliexpress. Back when I did it, you had to have it remotely programmed to remove CP and get everything working with the car, but there is now a way to get around all of that. The thread is on golfmk7.com.

It's not quite as bad as you think - it's mostly just upgrade the unit and then get it to talk to the car. It used to be really difficult, but as time rolls on, procedures appear.

Where did you purchase the unit?

Am I taking crazy pills... eBay.

These units where first available late 2015 and were being installed from the factory until 2018-19. Back then if you wanted a new one from the dealer you were typically looking at $5-600. No one doing the retrofit was buying them from the dealer. Back then they were around $300 on eBay.

It's unlikely any dealer has one in stock these days but expect the price to be at least the original $5-600, probably a good bit more.

Quick eBay search for the part number linked in the thread that has been linked (more than once in response to your questions, in multiple threads) shows several units for under $150. All of them "or best offer" so I say start at $95 and work your way down the list of sellers.

You can spend ~3x the money and have someone else do all of the computer-ing work for you as well.

Does anyone know if the ability to remove CP as seen in the vid that Cuzoe linked also provide a pathway to remove CP from other systems (such as my stalled heated-seats project for {her} GSW S)?

It does not, and if we're being technical CP is never removed or disabled. The (linux based) MIB software, depending on version, has vulnerabilities that allow access to the file system. From there it's possible to patch the routine(s) that would otherwise disable functionality when CP is active. But really CP remains active, and you will see those faults (in 5F Infotainment and 19 Gateway) but the MIB software gets patched to ignore the faults.

If you're doing heated seats is safe to assume you are stalled at BCM? If so, the BCM is commonly considered the dumbest module in the car. It largely consists of software controlled relays. Although I must admit I find it quite elegant from a programming/function perspective. What's the stall though... dealer won't adapt CP?

As soon as I hit post reply, I thought, "Cuz is gonna remind me that CP isn't removed!" Yes, the heated seats are installed, and I have the wiring loom, HVAC, and correct (uninstalled) BCM- which is where I was a year ago. I stopped at the closest dealer (who is probably among the least offensive) and they were both confused by my request and suggested a long wait. As with all things, I'd love to avoid the dealer if possible, I'm just not great at learning the software techniques. I've had the cable for Gregg's kw1281 software for a year and haven't done a thing yet, but a lot of that is also lack of time. Plus I need to make a map of the BCM first, me thinks.

You need an online account for component protection and SVM which will auto-magically take care of coding/adaptations. All the dealer has to do is follow the guided function for replacement of BCM.

I'll give the quick and dirty of how I've done BCM swaps at the dealer...
- At home, remove the trim pieces, disconnect BCM, pull it out of bracket, connect it hanging down in the footwell
- Go to dealer, give them the car in this condition along with the new BCM
--- They will drive car into the bay/garage, disconnect old BCM and connect the replacement (still hanging in the footwell)
- They go through the ODIS guided function for replacing the module, which will handle CP, pairing of keys (bring both), coding and adaptations
- Pay them, take your car home, put it all back together.

The BCM can be disconnected/reconnected without issue. Nothing is stored in volatile memory. No reasonable dealer should charge more than 2 hours for this. If they're nice (or just interested) you could get it done in less than hour. And in fact if they connect your replacement BCM and run a guided fault finding it will point them to the guided replacement function (if they don't know how to get there).

Thx for this Cuzoe. My notes from various sources say I need to make a map of the current BCM prior- is that still accurate?

In general, any time you're swapping modules, I'd be sure to have a complete admap (and whatever the "restorable" read of it is called, too) - adphex, or something like that (?).

It's a good practice so you can always go back to a working state. And it will let you compare things.

If your new (to you) BCM is the one called out by ETKA for your car then ODIS on-line will take care of all the coding/adaptations and get your car back to "as delivered" state. You would then make whatever tweaks/mods/changes you wanted, enabling heated seats for example.

Note that ETKA is going to call out the highline module for your car which was not in there from factory.
It will something like 5Q0 937 087 S (replaces 5Q0 937 087 Q and 5Q0 937 087 R)... 0857 Q is a low BCM, 857 S is a high.

But if the new (to you) BCM is not the one called by ETKA ODIS on-line is not going to do the coding/adaptations (can still take care of component protection and pair your keys). In that case you would NEED to use your backups in order to manually restore coding/adaptations.

In general, any time you're swapping modules, I'd be sure to have a complete admap (and whatever the "restorable" read of it is called, too) - adphex, or something like that (?).

Hex Backup (adphex) is available if you have have HEX-V2. It's not an option on anything prior. The old and new BCM's will be different part numbers. I assume VCDS will give some type of warning about that but maybe it will let you restore anyway. I haven't tried it.

 

[hskrdu]

Copy all. Thx!
I don't have HEX-V2 yet, but an "extra" older cable that I'm going to use for the RT upgrade program. The BCM I have (ebay) was listed as 5Q0 937 087N (and noted as MQB HIGH). Honestly, I just zoomed in on the photos to check for the pins at the right numbers, according to one of GolfDave's threads. I also waited for a listing from a Mk7 Golf/GSW, as I was thinking this might (somehow) be better.

What is the name of these units? I mean, if I do a Google search for what?

 

[Cuzoe]

Search by the part numbers listed in that DIY thread, search eBay. MIB 2 refers to dozens of part numbers, but you need the part number called out in the thread.

 

[jjpsuperdad]

Sorry, I’m technically challenged. I don’t even see the part numbers in this thread. I see other things people talking about.

DIY: MIB1 > MIB2 NEW SIMPLIFIED Method

Hi All, **11/2024 UPDATE - It seems that some of the sites are no longer active. I have tried to update this thread to reduce the number of external links. It may be very difficult to remove the CP yourself on your own now unless you have the exact software train I have.** Firstly, thank you...

www.golfmk7.com

Instructions are also in that thread. The patching is pretty technical. It's a certainly something I would have to look at several times before doing it myself.
