I just installed my AvicZ1 in my 2007 Dodge Ram last week. It has the Infinity system so I used the Peripheral CHYAH05 so I would still be able to use the stock amp.

 

I am not getting the voice guidance. Also fade works to the front but not to the back. I saw this issue a couple more places in the forum. The solution I read was to hook up the front outs on the deck to the rear ins on the harness. I tried that and it solved the voice guidance issue but not the fade issue. The system also did not get very loud when turned all the way up. I am not sure if I actually did it correctly though. Any ideas or solutions?

 

Sorry more of a home electronics guy than a mobile guy.
