Hands free interference

[spikey]

i have a nok 6310 and cark 91 fully fitted handsfree kit in my 1.8t 2000.

When you make a call, interference can be heard through the cars speakers

I have spoke with an engineers who stated that this is a common problem

Has anyone heard of this before ?

Are you using car radio mute through the standard fit head unit?

you get that if you run amp wires all bunched together on one side of the car. just for your info

yes i am running the radio mute through the gamma standard fit but using the additional nokia speaker

I would guess that its going stem from the Gamma headunit, not from the Nokia car kit itself. I have installed plenty of Nokia car kits, and have found them to be very good. All of these installed have been twinned with aftermarket headunits.

I currently have a Nokia bluetooth car kit for my 8910i running with my Pioneer screen in my Mk4, and its faultless. My guess is that its a poor quality car radio mute within the gamma unit, especially if you have been told this is a common problem by engineers.
