Hello folks,

I have a 2001 986 boxster with the Becker CDR 220 radio, amp, dash speakers, door subs, and rear speaker kit. I do not have the boise sound system. I would like to add factory navigation and found a PCM 2 unit on ebay 996.642.234.02. My question is about if it is possible to make the conversation to this nav unit. Since this is PCM 2 does that mean it wouldnt work with the amp? If it is possible what other parts do I need such as a GPS antenna?

Thanks

Aarron

Sorry, PCM 2 is for MOST (fiber optic network) cars - and the Boxster did not get that until MY2003.

There would be a lot more to change that just the NAV.

I think you would be better off with an aftermarket NAV.

Thanks!

I also noticed a different nav unit that had a cassette play on the top and a CD unit below by the HVAC controls, is that the correct unit for my car?

The correct PCM for your car is PCM 1. It looks like this...

I do not think the maps have been updated in over 5 years - which is a another reason to go aftermarket.
