Well, finally got the new Alpine ILX207 in and working, including the backup camera mounted in the alpine license plate holder. Still have to hook up the wire to the reverse lights switch, and install the SiriusXM antenna.
The radio cage wood trim on the top right side is loose and epoxy doesn't fix the issue. I need a plastic glue that's much much stronger.
Decided not to cut the factory harness and move the OBD port. Just didn't like the look of that procedure.
Driver's door grab handle (with the controls) came off the door in my hand - the tabs or whatever holds it in have long since broken, so I guess I'll have to glue that back in too. Sigh.
Anyway, still learning about the Alpine but it does have a volume control for the phone, and does have the option of having the sound come out of all of the speakers. So now, with the volume all the way up, I can actually hear incoming calls. Yay!
The Alpine allows for adjustment of the crossover settings for front, rear, and subwoofer channels - complete control including slope. It also allows for timing of each channel, which I played with a bit, and it actually helped.
Finally, the EQ is pretty dang good as well, allowing adjustment for each individual band (which is a frequency spread) then saving them in presets.
