PM UK-C200, you may be right about the HK option.

If you see "Logic 7" as an option, your head is configured for an external HK amp, which you don't have.

You need to go into DAS and either tell your head that you don't have an amp, or if you are using an older version of DAS, set "Force use of internal amp".

To the best of my knowledge, there is no way to do this without DAS.

Hi I have been for a long time reading your posts and i think you guys know alot about this upgrade, to make the long story i have a us model slk350 with audio 20 after reading alot i found that othe people have upgraded so i bought a new audio 20 ntg 2.5 and cables from Frank @Kabeldaviko + i bought an ipod kit ,talked with the dealer (service adviser is my friend) and the telematics guy at the dealer installed the radio,today my service advisor called and told me that the radio is working but it keep blowing the fuse and they suspect it was the adapterset from Frank,telematics guy today was off to talk directly with him, so ill call him tomorrow to know better whats going on, do you guys have any ide what it may be?maybe the adapterset form ntg 1 to ntg 2.5 or maybe the microphone cable????or something else?
I emailed Frank With the problem too let see what he gonna say.

Hey 5slk350,

Were you able to solve your problem?

Guys - Franks cable sets are for ROW spec heads, not US - you will need to swap a couple of wires around.

If you go look at Linuxpro's retrofit thread, I posted the pinouts for the US spec units.

PM sent to you - there's easier ways to get it fixed than to ship it over to me in the UK! ;-)
Hi UK-C200,

I have the same problem but it's the other way around. I've got a US Audio 20 NTG2.5 to put on a European SLK350 that has the old Audio 20.

Would it work?

Could kindly help?

Thx!

Cheers
JP
