From Audio 50 to NTG 2.5 with HK system

[ryo2000]

Hi all,

I've just installed a NTG 2.5 on my 2004 SLK 171.
I originally had an audio 50 with HK system.

I've bought the cable to kabledaviko and the NTG 2.5 seems to work except there is no sound coming out from the speakers.

I think I should bypass the AGW of the HK system or configure the NTG to use it.
I'd prefer configure the NTG...

Do you know how to do it?

Thanks in advance

Here's a link from SLKWorld.com. Adamantium completed the NTG 2.5 conversion and is very knowledgable. He encountered the same issue with no sound. Any questions, you can PM him. UK-C200 helped him and is also very knowledgable. Here's a simple answer from this forum. Link.

OK, thanks very much.
I hope this will help me...
