I bought my 75 with a Nokia phone holder installed and wired in. Can anyone tell me if it's possible to change the cradle for one that holds a Sony Ericson (that's the phone I have) and still keep the existing wiring. If so do you know where I'd get one? I can't see an obvious way to change it. Alternatively how easy is it to take out altogether and refit a cupholder which would have been there originally. It looks intrusive as it is and spoils the look and if it is no use I'd rather have it out.
