I have a Nokia 6310i so it seemed obvious to fit the Nokia CK-1W (update of
CARK112) Bluetooth kit to my UK Saab 9-5 (late 1998). I have read various
installation instructions online. Those that came with the kit are rather
Fitting has been straight forward. I bought the handsfree wiring harness
from my Saab dealer, and fitted the two jackplugs to the harness, together
with the power connectors, and the remote control button. All seemed ok.
On turning on the ignition and the phone the bluetooth is recognised (and
paired). So far so good. A call can be received - i.e. the stereo
speakers mute, the SID says "TELEPHONE", and all goes quiet - and stays
quiet. I cannot hear the incoming call and they cannot hear me. Similarly
if I try to make a call and try using voicetags the phone display simply
says "Not recognised" even though it does if not connected to Bluetooth.
It is as if the microphone is not functioning. Adjusting the volume makes no
I thought the built in Saab microphone may be faulty, so I plugged in the
microphone from the Nokia Kit instead, but it makes no difference. Nor does
it make any difference if I plug in the separate Nokia speaker from the kit.
I am puzzled. So far as I can see I have done the installation correctly.
The Bluetooth unit certainly appears to work - it talks to the phone.
I have not connected an aerial. There is no mention in the installation
instructions. There is a pre installed aerial cable but I have seen
somewhere that it is not required - so presumably the Bluetooth system it
simply utilises the aerial in the 6310i.
Any bright ideas? I suspect that I have omitted something blindingly
Many thanks to anyone who has read this far!
Ok, assuming that there is an exact similarity between the 2000 my 9-5
and 1998, then the following is what I understand to be true.
1) microphone (high or low level, doesn't matter) must be connected to
the phone, either through bluetooth or directly.
2) audio output from the phone (or bluetooth) must be connected to the
audio line inputs in the harness. If you have some test equipment,
I'd put a signal on the bluetooth output (and disconnect the
bluetooth), hitting the level control to the audio system to connect
the internal audio system to the signal generator.
3) I'd also check the bluetooth audio to the system, and make sure
that when receiving a call there is an output.
4) there is a telephone default volume, you might want to check that.
5) I'd also check to see that there is an audio output to the
bluetooth interface and thence to the phone.
I'm assuming that you have some test equipment, a scope, voltmeter,
signal generator... that kind of thing. That's what I'd do..
the bluetooth unit is talking to the phone, but it may only get a
status signal, on hook or not.. there might be something else you need
to do, I'm not sure.
The preinstalled areal cable to the phone goes up to the back of the
roof, and unless there is an onstar antenna, I do think it is just an
I'd ignore it unless you have a need for a wire going back there...
and the right front is the best place to put a telephone antenna
according to the dealer.
In the next month or so, I will be installing a phone and amateur
transceiver in the car. The phone will use its own system, and the
transceiver will use the internal telephone wiring. I'll have to
make a vox control for the speaker/microphone output to get the
telephone circuitry to operate, unless I decide to just have a switch
to mute the radio and patch the rig in.
