Parrot kit installation - Indentifying which audio system.
I'm trying to install a Parrot hands free kit into someones 2004 E85 Bmw Z4. I need to make sure I'm able to order the correct Sound on Top (SOT) lead.
The guy tells me it's got the factory upgraded audio system.
I just need you guys to confirm for me thats the factory upgraded audio system is deffinately the DSP system.
As far as I can tell the only other factory upgrade option is the Logic 7 system, but I think that was only available after 2006 (and this Z4 is an 2004)
I can find a SOT lead for the Logic 7 system but not for the DSP system, does that sounds correct?
Thanks for your help.
