My stereo/satnav has packed up due to corrosion of the terminals on the back so it looks like I'll need a replacement (cleaning the connectors didnt work).
Does anyone know what the difference is between the 6cd-565 and 6cd-465 units? I'm looking at breakers and ebay but wanted to know if I can replace my 565 with a 465 (or any other number).

Thanks.
