    Hi,

    I have a Nokia 6310i and I believe a Cark-91, (marked MCC-1 on the
    cradle back) car kit fitted to my BMW convertible. The cables from
    the car kit disappear into the depths of the dash. With the phone in
    the holder, the car icon appears on the phone screen, and when the
    phone rings the radio mutes, sound comes thru the speakers, and all is
    well. But when the roof is down it is almost impossible to have a
    conversation on the move using the car kit microphone because of wind
    noise, so I bought an Ericsson HB353 Bluetooth headset. The headset
    works fine when the phone is out of the car kit, but when the phone is
    in the cradle you can't make a Bluetooth connection – the phone
    instructs you to ‘remove the wired accessory'.

    With some experimenting I determined that the key contact on the
    bottom of the phone is the MBUS pin (pin 6). With pin 6 masked off
    with a piece of tape the phone will sit in the holder but doesn't
    think it is in the car kit – so it's held securely (and possibly
    charges? – although it doesn't say charging…), but will associate with
    the Bluetooth headset, and I was initially happy. But like everything
    in life, dissatisfaction starts to set in…

    What I would really like is to choose when I use the Bluetooth headset
    (roof down), and when it should act as a proper car kit, muting the
    radio, coming thru the speakers and so on (roof up). So I reasoned as
    follows –

    If I buy a micro switch and open the car kit holder and insert the
    switch in-line on the wire from pin 6 (MBUS) then with the switch
    mounted thru a hole in the side of the phone holder I can switch
    between MBUS closed (acting as a full car kit) and MBUS open
    (Bluetooth headset). And now we finally get to my problem; when I
    open the holder there isn't a one to one relationship between the
    contacts for the bottom of the phone on the holder, and the wires in
    the unit – there is a little PCB in there and 14 wires coming from a
    little white connector.

    I have searched high and low on the Internet but can't find any
    documentation about these wires and the function of each one. Seeing
    as I am not the glamorous lead in a Hollywood blockbuster, cutting one
    of the wires at random is not likely to deliver the desired result.

    The wires are arranged in the connector as follows looking from the
    back of the holder running from left to right

    Blank pin – no wire connected
    Orange
    Green
    Brown
    Light Blue
    Yellow
    Pink
    Red
    Light Brown
    White
    Black
    Grey
    Blue
    Purple

    One last thing – I live in the U.K, so if there are country specific
    differences in the cark kit then I guess mine is an English one.

    Any help you Nokia gurus could give me on this – a pointer to some
    documentation or some tips would be very much appreciated.

    My 6310i is at revision 4.80.

    Thanks

    Neil

    [Rest of long post snipped]

    You find there are enough sunny days in the UK to make it worthwhile
    buying a convertible..??!! Not in the bit I live in there aren't..! My
    bike sits in the garage for weeks on end moping because I don't ride it
    ;-)

    Seriously I can understand the problem, but I don't think there's an easy
    way around it. You could fit the HSU-1 handset but then of course the
    handsfree bit would go out of the window (or wherever it goes in an open
    top..!!)

    BTW if you find a way of opening the phone holder without bits of wiring,
    springs, screws and whatever disappearing to the four corners of the
    universe never to be seen again, please let me know..! I'd like to fit a
    switch to interrupt the charging supply, as I don't believe in continually
    topping up a battery every time I put the phone in the cradle. At the
    moment I am using a bit of sticky tape but as you say it's not a good
    solution.

    If you're using a lithium ion or lithium polymer battery, those top-ups are
    exactly what your battery wants and needs. NiCd and NiMH are a different
    matter, though.

    Id say go with a lithium ion or lithium polymer battery top-up

    I disagree. I have several Li-Ion batteries, some of which are over 3
    years old, and although they aren't as good as new ones they still hold a
    charge. I have seen similar batteries die in less than a year when
    continally topped up. I don't completely discharge them, I wait until I
    get a "low battery" bleep from the phone.

    In any case, I'd still like the choice.

    Now Ivor, I think you are too keen to find excuses not to ride that
    machine, a little lashing rain never hurt anyone! :-)

    The back of the Cark-91 holder comes off without a problem, it's held
    on with six very small allen screws.

    I have a switch from Maplin - Ultra minature SPST toggle - part no.
    FH97F which will fit once a small hole is drilled in the body of the
    holder. All I really need now is to know which wire to cut into...

    True, but it takes me 2 hours to clean the bike afterwards ;-)

    Thanks for the info on the switch, I'll have a look next time I'm passing
    the local Maplin shop.

    Just relating what the battery professionals say.

    Well they would say that, wouldn't they, after all they want us to buy new
    batteries..!

    If that were true, they'd want us to top up our NiCd and NiMH batteries
    twice a day, right? And we'd still be using NiCd (which is a great battery
    format, *if you use it right*, but almost no one does use it right).

    Ok, I'm being cynical somewhat, but NiCd and NiMH are well understood
    these days and nearly everyone knows you shouldn't top them up. Li-Ion and
    Li-Polymer are still relatively new in comparison. I've only come across
    one battery type that likes topping up, and that's Lead-Acid. Not seen one
    of those to fit a phone yet ;-)

    This is my personal experience over several years, YMMV as they say.

    CARK-91 wiring 14 pin connector

    I know this was originally posted a long time ago. Does anyone have the pin readout for the 14 pin connector used in the CARK-91 cradle?
    The wires are arranged in the connector as follows looking from the
    back of the holder running from left to right

    Blank pin – no wire connected

    I would say, if you don't know what it does, leave it alone :-P
