Rid myself of Dakota Infinity System, install blutooth stereo?

I think that dual media 3 band EQ "joystick" fader Infinity is quite possibly the best factory head unit installed in any vehicle up to the modern "synch" style units.

That said, the one in my 2000 Dakota started loosing the FM tuner last year.

I bought an open box Pioneer 4400 series from a friend, and I LOVE it.

No bluetooth, but it has USB and aux with adjustable input levels.

I liked it so much I bought another one just like it for my 73 Satellite, and I'll likely buy another for the wife's car- so I can have the same interface.

My rear speakers in the Dakota are bypassed and upgraded Pyle 6x9.
The fronts are still through the amp. I just keep the fader adjusted so the fronts don't overdrive.

There's a "secret" cheap wire harness kit (available from ebay) that matches the harness plug at the amp, so you don't have to splice if you don't want to.
The part number is on FxBO somewhere.

The only thing I don't like about it (or really any modern "soft" interface) is navigating five layers through the menu to adjust the EQ, and then doing it again for the next song. I think I'm going to get one or two (F and R) old school passive EQ units to resolve that.

My Satellite has 10" woofers and component tweeters. The 25-ish WPC is not really enough for them so that car will get about a 100 WPC amp.
