Radio "dead" after replacing battery. I HAVE THE CODES! (But no way to enter them)

[gowestwarho]

I see a lot of info out there about how to find your lost radio codes and whatnot, but that is not my problem as I have my codes. The issue is that after 1)having a dead battery, 2)replacing said battery, and 3)having the car sit unused for a week while waiting on a replacement coolant tank part, I NOW HAVE A DEAD-SCREEN RADIO AND NO WAY TO ENTER THE CODE OR TURN ON THE RADIO.

I can see that other people may have experienced this phenomenon but I can't seem to find anyone with a published solution as everyone seems to digress into a discussion of where to find your radio codes, etc.

I assume that there is some sort of arcane Porsche security gremlin at work here, and that I need to follow some other sort of procedure in order to get my radio to accept the code and unlock itself. But without the radio showing any signs of life at all, how do I get into this?

Or is my radio now dead for no apparent reason?! (e.g., it was working just fine up until the dead battery and service work time-span).

I hate to invest in a replacement radio until I can ascertain what would make it suddenly die(?) Never in all my years of auto ownership have I seen a radio just "go silent". So what's up here?

Sorry about that. I have a 2001 Boxster S with the stock radio. Thanks

If the unit's screen is a total blank then it may have a blown fuse which is located on the back of the unit, you can also try to remove and reattach the faceplace first to see if that works (I think your unit has the removeable faceplate.)

[gowestwarho]

I have already tried the faceplate removal and reinstall. But you bring up something new....so there is a fuse integral to the radio itself?? Behind the radio?? And in addition to the standard fuse(s) in the footwell?? So I'm going to need purchase a radio removal tool now just to check the "special fuse"?? Do I understand that correctly? (and thank you!)

[boxster6354]

Correct:

You will need the removal keys, PM me an address I have a set and can drop them in the regular mail.

(I have never tried to remove the fuse from the back without removing? Maybe you can)

It is a 10amp red fuse in the back, you should have an extra in the footwell fuse box.

would unhooking the battery again and then hooking it back up help?

I had a family members boxster do the same thing. I was able to get the removal keys in a pack of assorted ones at walmart for $4 back in the stereo stuff. Uhggg... I hate to refer anyone to walmart (sorry). His fuse was good and after removing it several times the radio did come back on intermittently. He ended up having to replace it with an aftermarket one. It was a cdr220 I believe. Good luck!
