OEM subwoofer software upload

Post by eapowers64 » Mon Jun 24, 2019 11:12 am

Hi, I have a 04 xc09 that originally came with the High Performance sound system. I have added an OEM sub from a scrapped 04 xc90 and tied it into the MOST system with the appropriate wiring harness. Does anyone know the particulars on what software update I need for the amp to start encoding a signal for the sub's amp via the MOST system?

Old doc https://www.volvotechinfo.com/index.cfm ... 090109.pdf for reference.

Believe it's PN 6849980 to activate the subwoofer.

I pulled my subwoofer from a junk yard donor car. There are two used ones for sale on ebay.
