I got a Parrott CK3100 installed in my ED30 when I bought it - was well chuffed!!!! Till I kept getting callers saying they couldn't hear me properly. I got another ICE garage to relocate the Mic off the Drivers Pillar, to the centre headliner, but still no joy.
I ended up ripping the **** out of the dash one day when it totally ****** me off! My mate has the same unit in his Van and I know what people are talking about - he sounds sh1te, really distorted. I still have it plugged in but it doesn't switch on now - wonder why
Personally, I wouldn't bother with the Parrott - please tell me what you guys did differently if you had any sound issues.
BTW - I had a Golf Plus yesterday on Courtesy, with a RNS510 in - they are very good, but what about the 4 digit Postcodes (ahem, that went out with my old Navman 4 years ago!)>
