Ericsson HCH-30 & HCA-10?

Hi,

I have an Ericsson HCA-10 car kit installed in my car, using it with
T39m. All is okay, except the phone is 2 years old and the keypad is
getting a bit temeramental.

I want to replace the phone with a newer one, but I need the car kit!

Is there any way to use the HCH-30 phone holder with my 1-year-old
HCA-10? I don't mind re-wiring the connector cable, does anyone know
if this is possible?

Thanks,
Richard
