I'm working towards joining the z4 coupe owners group .. just a quick question if a z4 has the sat Nov professional opinion does that mean it comes with the uprated 10 speakers system?
I believe BMW always sold the Nav and speaker upgrades separately so you’ll need to look for the extra speakers behind the seat and/or do a vin check to confirm if a prospective purchase has the upgraded audio.
My German LHD E86 coupe shows 'Sat Nav Professional' and 'Professional Hi-Fi Loudspeakers' on the factory spec sheet.....I assumed it was unrelated...the sound system is along with a 6 CD changer. So far I have detected 8 speakers from front to behind the seats .....another two could lurk under the footwells?
Firstly welcome to the forum OP - and hopefully to Coupe ownership.
They are definitely 2 different options - my first Coupe had the HiFi professional 10 speaker DSP system but had no Sat-Nav! Well not until I plugged in my Garmin!
To be honest I wouldn't be too bothered about having a 10+ year old Sat-Nav, but the DSP stereo is worth having - it could probably make your ears bleed in such a confined space! :lol:
But if I was ever searching again my first priority would be M-Sport seats (standard on Sport models, optional on SEs) and Bi-Xenon headlights (optional on both).
