Hello all
I have a big problem. My car is without navigation. I decided to change it, I bought the navigation and now I have no idea how to connect it
Can someone help me?

IIRC, someone on eBay was selling custom made harnesses to convert 06-09 ISx50's without nav to nav:

I read it, the problem lies in the fact that I have other harnesses, I need to diagram the harness from the radio / cd. I'm looking for three days and found nothing.

 

You both the wrong unit (which is way cheaper than whatt you needed). The system you need to buy is 06-08 unit not 2010 and up!!!
The unit you bought is HDD base which is totally different which the retrofit guide that you are reading. When you need to DIY, make sure to read the correction info.

 

Navigation and Radio 06-08 do not fit into my model, I have a different air vents.
To my model fits navigation 2009 up
