Advice Wanted!! K750i Car Kits

Can anyone please advise me as to the car kits avaialbe for my K750i. I know SE make one called the HC...60 but I already have a Nokia CARK91 and I do not want to t ake it out completely.

I am looking for a Car kit that will charge my phone and allow me to take calls at the same time, not too bothered about the cutting the stereo out bit.

I also have another Q and that is does the HCH60 or 61 Holder take the CLA-60 charger, or what I mean is, is there someway the cigarette lighter charger plugs into the bottom of the holder as I was thinking of buying these two components.

As you can see I don't have a clue, hence why I am here pleading for some sanity!!!! Aaaarrrgh.

Thanks, if you can help, thanks if you cannot.

P.S. I am just 3 Referrals away from getting my FREE XBOX 360 if you want one or would love to help me please click on the link below. As far as I can see it is not a scam and has even been tested by the BBC.
