Suggestion · Original poster

If I change to an aftermarket unit like the Pioneer AVIC F900BT or similar, do the input levels to the Bose amplifier need to be adjusted by using an adapter like for example a Dietz interface ?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hello, I have a 2002TT with PCM1 and factory Bose - no Most version, the classical copper variant . If I change to an aftermarket unit like the Pioneer AVIC F900BT or similar, do the input levels to the Bose amplifier need to be adjusted by using an adapter like for example a Dietz interface ? I changed the headunit in one of my cars, a Mercedes S class and there I discovered the need of an adapter for the voltage levels. Any qualified statement would be appreciated. Thanks Peter

POST 4Original post

That is a sweet TT, it looks lowered? sorry Im not an authority on stereos, my idea of an upgrade is this:

POST 5Original post

Nope, I put a AVIC-Z in my 02 with bose, no issues and no Dietz interface needed. Just a custom wiring so I would not have to cut any factory wires. Welcome to Rennlist!

POST 6 / ORIGINAL POSTEROriginal post

Marc, thanks for the info, that's exactly the info I needed. Redridge, it's not lowered, that's the standard setup in Europe. There would be a sport package which sets the car even lower, but I decided to got the standard suspension way with tiptronic - I drive around a lot in cities. Attached is a picture of the interior:
