This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.
