Jose,

Thanks mate. The wiring harness was something I made myself. My satnav kit only came with the connectors (the wires had been cut at the connector) so i had to build the wiring harness and figure it all out. The wiring diagrams in the manual you talked about was really helpful and beyond that, lots of trial and error.

If you have all the wiring lengths, all you need to do is join up the wires. That shouldn't be too hard if you are electrically minded, just be careful with shielding (remember there are some video cables there). A few practice runs with a soldering iron and you'll be right. PM me if you need more details or want me to do it for you.

With regards to the code, I didnt realize they had a code (e.g. i did not have the code for mine but i did not need it). This may be different for Accord Euro's in Europe/Spain.

Hope this helps!
