VW Touareg no sound radio delta and amp

[mellon]

Hi,
VW Touareg, Radio Delta 7L6 035 195 vwz4z4, amp 12CH 7L6 035 466. In radio I have 4 errors about speakers line and in amp, gateway and cluster 00464 about not communication with radio J503. So, I have communication with radio. Gateway not have long coding, in amp is 000006. I coded radio many times with different values and nothing. No sound. Maybe there was navigation unit. The car was bought with this problem.

I bought navigation mfd2 dvd for touareg. In radio and amp no errors. In gateway and cluster 01304 (no radio communication) and still no sound. Second amp the same no sound. SO maybe gateway is to old? Please help.
