I have had my 2015 CR-V 1.6 I-DTEC SE-T for about a month now and love it so far. I have just had a tow-bar fitted and they had to disconnect the battery so it's now asking for the security code when turning on the sat nav / stereo. I have the Anti-Theft ID Card that came with the car, but that just shows a serial number that is a word and no code. (6 Alphabet Chars) The same code is shown in the service book. The unit seems to be asking for a 4 digit numeric code, so I'm rather confused what / where this code is ! Can anyone help me ?
