I installed my old f700 on a friends '10 Si and integrated the oem amp, there was some initial noise making me wonder if it might be worth putting some ground loop isolators in line with the preamp outs on the z140 when you do the install.
supposedly it can auto calibrate the EQ based on your cars acoustics using an optional microphone, i have yet to see if i can use the auto calibrate mic from a reciever i have lying around to do the same thing
I have a z140 in my car now, originally ordered a z130 refurb but got sent a brand new 140 instead. I love it, sound quality is pretty impressive, i dont think youll be disappointed there. It does have some quirks as far as the interface but that may be a function of im used to how the f700...
I did cupholders on my car, they were amusing, but when i did the new stereo install i knocked one of the wires out and now my cupholders dont glow anymore, but i dont really miss it
having the interior kit from honda is a great starting point to add other leds elsewhere, you can tap in a bunch of additional leds and keep them all run off the same oem switch
wanted the new maps and features, pioneer had pretty much abandoned the F series as far as OS updates and potentially maps. The Z units have been supported since the z110 came out and you can get the new models software loaded on the old ones to give most of the new functionality and maps...
