Hi i really need some help with this problem .. now own a 1994 vauxhall
astra and was given a philips Car400 that should have been fitted in the
vehicle but was replaced at some time. i now would like to refit the philips
unit but i have no idea what the security code is ?

the id marks on the unit are as follows

Philips Car 400

s/n GM0400V1659723

DC396/75E

2WA01

No: 90 532 621

Is there any where that i maybe able to get a dump file with the security
code ?
Or any other way of getting a code without having to pay main dealer service
charges ?

Thanks for any help you maybe able to offer
