Cark 91 Conversion

I have 2 Cark 91 from previous cars that were professionally fitted and
wish to install them in 2 new cars myself.
I also want them to work thru the radio and mute for incoming calls.

I removed them quite easily, however when I went to install them the
brackets would not fit and I found the cars did not have the interface
connectors to reconnect. I also want to convert the system for pop-port
phones.We now use Nokia 6230i and 6820 phones.

I assume from this I need additional interface leads and brackets which
will be different for each car.

Does anyone have a step by step guide to for this conversion and
installation.


Many thanks in advance.

Tim
