  1. Hello ! I have a 996 C4 from 11/2000, PCM1 8 bit. The aim is to change the nav reader (ref xxxx.00 EFR) to 16bit reader (ref xxxx.03 EFR). As the PCM is stricktly the same on 8 and 16bit nav equipped cars, it seems swapping the reader should be ok. (software update needed ? PONA642 ?). Actually, I can buy the inside of the nav reader straight from Siemens (mechanical part (cd eater) supplied with the onboard chip fixed on it.). Should work ? Will the code still be the same for navigation ? I appologize for my english skills as I'm French :-( Thanks !
