i took my cousins KDC cd player and fitted it into my car. a while back the battery died and i replaced the battery. ever since- i have not been able to play anything cause it keeps asking for "a code"
would anyone know what this "code" might be?
any help will be appriciated.

Kenwood stereos have a PIN code security feature. Your cousin may have set a code. Try the default code (see manual).

To protect the HU or maybe if you want to piss your g.f off by not letting her listen to music

Security. If any one takes it, they should not be able to use it.

@madan, The PIN should be part of the papers (of the HU, if purchased separately), or with the car's papers. Get you cousin to contact the dealer he got it from. Or atleast get the original invoices. Have the dealer get the PIN for you.

The default pin is there in the manual

and if its changed then the guy who changed it might be knowing

or if he has forgotten then can be resetted by the Kenwood dealer.

You mentioned your installer entered a code. Go back to him. I checked. There is no default. And reset does not reset the code. The idea is to render the HU unusable if stolen. The installer should not have activated this feature (off by default) in the first place.

Dont think the installer has a choice on this. AFAIK, there's no default - that's the reason I had suggested trying to get the HU's papers.
