Suggestion

Yes...the MOST system is a digital system between the head unit and amp....so yes you would need to bypass the the stock amp...you could either wire the speakers to the head unit depending on your system (the bose may not be that easy) or replace the stock MOST amp when you also replace the head unit.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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

i apologize for my insufficient search capabilities. i swear i've tried, but all i can come up with are discussions about whether X aftermarket head unit will interface with the MOST system, the merits of handheld gps vs. head units, etc. questions: (a) do all 996's use MOST, certain year ranges, or just the Bose-equipped systems? (b) can someone point me to a DIY of installing a double-din unit in a non-MOST equipped 996? thank you in advance

POST 3 / ORIGINAL POSTEROriginal post

first, thanks for the help. is the MOST system 'intrusive' enough that installing an aftermarket head unit in an 03+ would require re-wiring of the speakers directly to the new head unit? i.e. do all MOST-equipped systems run an amp, etc. that would need to be bypassed if/when installing a new head?

POST 4Original post

Yes...the MOST system is a digital system between the head unit and amp....so yes you would need to bypass the the stock amp...you could either wire the speakers to the head unit depending on your system (the bose may not be that easy) or replace the stock MOST amp when you also replace the head unit. I think there is something you need to do to the car as well via the ECU....so the dealer's service department must tell the car there is no radio present. If you have the MOST bus, I would have the system installed professionally by someone who has done MANY of them before on MOST bus Porsche's...its not just like swapping the head unit....
