I gt a Parrot ck3000 kit in my mk3. fitted myself...simple piece of kit and never gone wrong on me and its been a good 4 yrs since i had in. Cant complain. For those with amps, you will find it only mutes what runs as oem speaker outputs from the radio..however, if you'r running a none original head unit...then the YELLOW wire tha is loose on the parrot kit can be connected to the available MUTE input on most aftermarket radios to then MUTE the amp aswel or otherwise anything running from the low level outputs of the radio.
I know this will work however, i've been lazy and left mine how it was before I installed the amp n woofer etc...so wot i'm experiencing at the moment is everything mutes but the subwoofer in the boot..lol. but i got used to it even tho i no how to fix it.
Rite...regarding the Mki9000, Mki9100 and Mki9200, they all use the same brain housing...but they are all very much specific to the type of kit part number you have...e.g. if a brain goes wrong on a i9200...you CANNOT use a brain from an i9100 and vice versa.etc..
They are however a common cause to Parrot kit issues. As correctly asked by a previous comment, If it is a Mk5 golf or above, chances are you had to use wot they call an SOT lead (Sound On Top - SOT-976) to convert the oem harness which is the 40pin quadlock (square) to a means in which the parrot will understand (standard ISO). Same lead used for most new VW's and Audi's.
Even if it was an earlier golf, you will notice that because of the backwards power feeds i.e. permanent and switched live's, you will have to swap the in line fuse holders over that are on the Parrot kits harness (red to orange and orange to red). The idea is that IDEALLY you WANT the parrot kits with displays to say "goodbye" when shutting down. If you find that the kit just switches straight off upon vehicle shutdown, then that is an indicator that the power supplies to the kit are the wrong way around.
It has also come to my attension that sometimes where the wires have had to be tucked away behind the radio quite tightly, you can often experience stretching and pulling of the wires that have the fuse holders on the kits loom. this can temporarily knock a kit out and cause it to short out and crash.
Hope some of this information helps.
