Testing
Turn your key to the MAR position. The radio should open asking for code!

Insert the code that the seller provided you and voila!!! It works!
Don't try to insert codes in random because each time you insert a wrong code you must wait to enter it another time and after 10 wrong attempts the radio will be blocked.

That's it! Enjoy your new radio!
Something more!
Because the radio is from another car and we connect it to our CAN network, the mileage will flash at your dashboard meaning that something is wrong. That's because the radio is "foreign" to your ECU. It is usually fixed with a "PROXI alignment". Your local dealer or garage will be able to fix it conencting your car to a computer and making the alignment.
That's all! I hope that it is helpfull. Please send any questions or remarks below. Thank you.
