Hi there,
Can you help me to solve my car radio installation problem?
I don't know, what colors mean on the audio connector H1.
The first one is the battery and next to that is the ground.
Other colors are mistery.
Thanks in advance.

 

We don't have the H1 here in the US but the connector looks similar to other Hyundai models.

Here's the same 16-pin connector (16P) for the head unit in my 2006 Tucson.
Remember, the picture below is of the female port on the HU so left and right are opposite of the male connector you have.

 

Thanks indeed.
I have wires/pins only at the highlighted places.
7 is O.K. for power but I used 6 for ground and the radio has turned on.
