02 Car kit to gps mouse - muting easily solved !!!
I have just fitted a haicom GPS mouse to my friends O2 xda carkit.
Having read all the problems about muting and having to fit a relay on the stereo mute , I thought I would look a little deeper into that small black connector (8 pin connector)
I discovered that on turning gps on (on the xda) the stereo would mute instantly , I traced this to a 6v signal being given on the purple wire (pin 8 )
I connected pin8 to pin 2 (black (gnd) ) this did the trick - the gps now acts as if it is a factory installed gps system - only mutes when directions are given and if you turn voice of on gps it never mutes
Hope people find this useful
