    I've searched and read numerous threads but couldn't find the answer.
    I am about o buy a 2005 Prius II with JBL system and would want to change the headunit to a Kenwood 2-DIN unit.

    Can I just replace the headunit and will it work with the JBL amplifier or do I need additional equipment? I am asking because I've read the JBL amp has a fixed level balanced input.

    Having looked at the wiring diagram for a 3 Plug JBL amp, I would think the amp is driven by the headunit. The volume controls all run to the headunit and not the JBL Amp. Be aware there are 2 types of JBL Power Amps, a 2 plug unit, and a 3 plug unit. I have a 08, but I have heard from folk wanting info that their amp only has 2 connectors, whereas mine has 3.
    One note to consider, if you have the JBL pkg, if you remove the headunit you will lose the Nav guidance voice!
    There are a number of folk out here that have done marvelous things with Stereo installs. I am thinking they will pipe in at some point. .....F8L.....
    If you would like a copy of system wiring for the newer 3 plug amp system, PM me, I will email it to you!
    Good Luck, let us know what you end up with!

    I am not planning to use the outdated stock navigation or bluetooth, that's the reason why I want to upgrade the headunit but I'd really not want to replace the JBL amp or speakers.

    BTW I am based in Europe and I've read somewhere that the EU JBL amps might differ from the US ones?

    I want to change my HU on my 2005 with jbl, nav, and bluetooth also. Maybe there is a guide someone created for one with stock JBL amp out there? I want to know if I will lose bluetooth to my phone.
