Fitting Alpine Sat Nav to Impreza Estate

[Laurence Baker]

I have an Impreza year 2000, and I want to fit an Alpine Sat Nav unit
INA-N333R.

Every Auto Electrician I've rang has had no experience of fitting one, and
are little hesitant about it.

Is it that difficult?

Can anyone help me with info at all about fitting or the whereabouts of any
circuit diagrams online.

Thanks
