Hello everyone, I bought a used volkswagen Eurovan GL '93 model two weeks ago. The VIN is WV2KC0701PH066690. All I see on the radio screen is the word "SAFE" I understand that it is anti theft coded, I can't find the unlocking code inside the manual. The manual said the code number should be four, starting with 1, So I pulled out the radio yesterday hoping to get the code but what I saw instead was the numbers VWZ5Z27N0606815 and the serial no. which is 17679. I dont know of any dealer in my country (NIGERIA) that will assist me decode my radio. I will be very grateful if anyone can help me. my e-mail address is opunarms@yahoo.com
