i have done quite of bit of searching on this forum and can't find anything schematic for the hu
i found the schematic for the amp but that is not where i am tapping into
i see a lot references
i see few links to pics that do not exist any more
i ended up forking over the bucks to helm this morning
(god i hated to
i am spending like crazy to make this damn thing work)
but i would really appreciate it if someone can post a detailed schematic of the hu and the components
cause i got all the parts (or at least all should be available in the next two days) and i am currently stuck
and i am tired of driving around with my whole car (at least on the inside) taken apart

 

First, you should detail exactly what you're trying to do. Without exact details of your project and what you're trying to accomplish or the experts here wont be able to help you. I know that you need the HU schematic, but i'm sure that there's more to this than just that. Trust me...

 

well i have done enough research on this forum that i believe i know how to set up the system
what i need now is info on what wire belongs with what which is why i need the schematic

but just in case this is what i am doing
adding a bluetooth amp equalizer and new speakers

i will tap into the hu preamp signal with soundgate locprea
run it to equalizer that i will install on the arm rest to 4 channel amp in trunk to speakers etc
the parrot bluetooth ck3000 that i bought i will tap into the nave mute as well as the nave l r and grd (i dont have navi in my car)
i will use a loc to send preamp (bluetooth has its own amp) signals to hu thru navi slots
use grd loop isolator if necessary

so there u go
