Yup. I figured that much - CH32-19C164-BC or CH32-19C164-BD. Well - I have an amp for sale 😉.
At least I know where the problem is, and I can sort it out by buying a new one. But I still have the issue with the speakers. The dash one was easy - the one I've bought fitted perfectly, plugged in the existing harness. but I guess I still need to solve the rear d-pillars ones, right? And not only fitting them, but also somehow figuring the wiring.

The -AG version is the "same" as -AF, just an update of some sort. Will also be compatible, just plug & play.
You need the additional speakers, which are available as complete d-pillar trims, plus the center speaker that goes in the dashboard. There is some wiring missing however I have made up some "retrofit harness" to solve that problem.

Hi. Would it be possible to buy this "retrofit harness" from you?

Retrofit harness Discovery 4

If you wanted to go a bit further here, it's also possible to upgrade from the 11-speaker 600W Harmon Kardon system to the 17-speaker 1200W Harmon Kardon Logic7 Surround system. I've done this on a few Disco4 / LR4 now.
If you need to buy a replacment amp anyhow, then why not get a Logic7 version and go for an upgrade...
The Logic7 amp is CH32-19C164-BC or CH32-19C164-BD.

However you do need some software changes to enable the Surround functions, where are you located? I might know someone nearby who could do it. Or if you have a Nanocom or IID, it's possible to do the software changes with those.
You can also just fit the Logic7 amplifier in place of the non-surround one, it should work the same without any programming, have seen this on several other cars that have been upgraded, as an interim fix.

I'm in USA and working on retrofit Discovery 4 2013 (LR4 here) to logic7 from hi-ice
Do you have any contacts in USA who doing wire harness retrofit or if you can share part number for pins and plugs used for harness that would be appreciated. I would love to crimp my own harness to increase bond with my car, I love DIY myself
Thanks in advance
Kind regards,
Vlad
