Fitment and compatibility

The manufacturer application guide dated November 2020 lists the following BMW mounting applications for this model. These are selected closed year ranges from that guide, not a complete list and not a guarantee for every Australian factory audio option.

Series Chassis Body Guide model years
1 Series E81 3 door 2007 to 2012
1 Series E82 Coupe 2007 to 2013
1 Series E87 5 door 2007 to 2011
3 Series E90 Sedan 2005 to 2011
3 Series E91 Touring 2005 to 2011
3 Series E92 Coupe 2005 to 2011
3 Series E93 Convertible 2005 to 2011

The same guide pairs the single 2 ohm UP W8BMW-S with UP 7BMW for the stated HiFi option 676 system before mid 2019, or UP 7DSP routes for the stated Stereo and RAM systems. The RAM route requires the specified MEC ANALOG IN and harness. This does not establish compatibility with every Harman Kardon system or newer RAM generation.

Confirm the Australian build, original under seat enclosure, factory audio option, amplifier and connectors before ordering. The guide is dated and does not verify later facelifts or an unspecified MINI model.
