Hi, I met a problem on my CayenneS 2012 (Bose Sound)

A month ago, I retrofit head unit by myself from CDR31 to PCM3.1.
At that time, every function (BT phone, BT Aux, Aux, Navi, Map, and compass) is working even if i didn't do wiring.

However, recently,
I can only use FM/AM/DISC/AuxBT through DISC option menu(BT switch on).

Probably, i didn't put the activation Code for my PCM3.1. that's why it can not work well.





Does someone help to know where can i buy the Code for the belows?
- BT (Phone)
- UMS(Universal Audio interface aka UAS )
- VIN : WP1AB2929CLA50248

As far as i knew, Navi, Map, Logbook, Voice Control, SDARS(XM Radio), and Offroad Navi aren't necessary feature on South Korea.

Regards,
