Radio Code ?

Recommended Posts

I bought my 2004 Boxster S used from a local dealer and has the CDR23 radio in it. Looking to install the PNP rear speakers but do not have the radio code once I disconnect from the battery for installation. Is there a way I can obtain this code? Thanks

On a side note why do you have to disconnect the battery/radio when installing the PNP speakers?

CDR23 radios are electronically coded to the car itself, programmed at the factory. No separate, owner-entered code is required. If you disconnect the battery or remove the radio, once everything is reconnected, the radio checks itself against the coding from the car. It's a transparent process, accomplished without intervention from you.

Installing the speaker kit has you performing steps like routing wires forearm-deep into the dash. Disconnecting the battery when performing service like this is a safety and vehicle-damage-prevention measure. Safety, for example, from accidental ignition of an airbag. Vehicle damage, for example, from shorting a very expensive control box.

I recently installed the PNP rear speaker kit. The kit requires a wire harness to be threaded thru the passenger side door sill where airbag controls are. In addition, you do need to pull out the radio to get the harness attached. I always disconnect the battery whenever I am fooling with electrical connections.

BTW, you'll like the kit; really changes the sound system (though I rarely use it because I enjoy the sound of the car!)
