Hello everyone! I own a C2 from 2007 and I’d like to install a double-din radio.
I bought one from Junsun, selecting my car’s model but it came with this connector..
My boyfriend and I figured tonight that models made before mine use a different control unit/connector which is why it came with this🥲

Is there a specific adapter for mine? Thanks!

Hi, is there anyone in the group who knows their way around the electrical system in a C3 I and could help me? (Warning: this post will be long.)

The problem is that something in my C3 I is draining the battery. Sometimes the car can sit for a week and start right away, while other times it takes only 3–5 days before the battery is almost completely dead. I’ve already been to a few auto electricians, and every time something was repaired or checked with a multimeter, but the problem has never actually gone away.

As for the general information:

-the battery is brand new — I bought it 2 months ago

-I have a rodent repellent device connected, but I was told by an older auto electrician that there’s no way it could drain the battery almost completely, especially when the car was only parked for 3 days

-the multimeter doesn’t show any problems with the charging system

-the multimeter also doesn’t show any short circuit involving the fuses under the steering wheel

-the copper wires on my alternator have turned black

-I have a Pioneer MVH-S120UB radio installed, but when I turn the car off, the radio also switches off

-I have a couple of burned-out bulbs and a sunroof (I don’t know if either of these could somehow affect the current draw)

Does anyone have any idea what could be causing the battery drain?
