Head unit CDR 210 problem

[Ahnospell44]

I went to get into my car this morning and low and behold, it doesnt have sound. I have searched and tried all of the things on the forum, but I was wondering, do i need to replace the head unit? the unit is a cdr210, out of a '98 boxster, I want to atleast get the cd back out thats in it, but as far as I have tried, nothing. Does this mean that the head unit itself is dead? I have tried the following things:

1) press the on button

2) press and hold the on button

3) press the on button and tried to hold the 8 and 0 buttons*this is as per another post i saw to eject the cd*

4) disconnected the battery for 20 mins

5) took off the climate controls to 'jiggle the wires' in the back of the unit

6) give up and come online to find an answer.

now, obviously, either im retarded or i didnt try enough steps, so please post back as soon as possible, porsches just arent as much fun without the sound, the words of my 86 yr old grandmother.

Thanks in advance with any help

Ahnospell44,

uuuuhhmmm, Simple check but did you look at the fuse. It's unclear from your posting whether the unit has power but is just not functioning or has no power which might be the fuse.

Should be B2.

Second row of fuses from the top. Second fuse from the left. Should be 7.5 A.

alright, a trip to the advanced auto down the street, and 3 fuses later, i think there is a short myself. any thoughts? ive been having a problem with the CEL, infact there was a P code about the "aux output/input". Is there any way i could upgrade the fuse to a 10A? or a 20A? or would that just pop a higher fuse too. I'm trying to figure this out without a trip to the stealership cause im broke, and want to fix it cheap. Thanks for any replys

A higher rated fuse will not fix the short/problem.

The only things (that are supposed to be on that circuit) are the radio and Nav system (if you have it). Any 3rd party addons? Has the radio been out of the car recently?

What was your P-code?

You also mention in your original post "the unit is a cdr210, out of a '98 boxster", is this a new unit that you put in recently? There is typically a cause and effect item that created the situation. Can you think of anything that changed in the last week.

No this head unit has been in this car since we bought it in 2k, and now all the sudden it just recently has started falling apart, we dont treat it bad or anything, so we're all confused in my local family. I stuck a higher rated fuse in at 25A, and that fixed it for now, but I spoke with the last person to take it to Porsche, and they said that about 6 months back there was a problem where the car security system locked them out of the car, and they couldn't start it no matter what. Now, Porsche said that it was a short that they fixed, then all the sudden this problem comes back, I havent recieved any P codes, other then 1123 and 1125, which are lean running codes, and a aux in/out problem for the CEL. This car has been plagued with nothing but electrical problems since we purchased it, and even beyond. There are no 3rd party installs the car is completely stock, except for tires and alignment kit *because of a problem with the original alignment 'tierods' failing, and the original owner, didnt care to have stock back in and wanted aftermarket* no other fuses were blown, so i dont understand it.

Thanks for the help

This is certainly a challenge to figure out. I was wondering if you have had any water leaks inside the car. Specifically is there any water under the drivers seat. You mention in one of your earlier postings that the prior owner had a problem with the security system. Some owners have had a problem with the drain holes under the convertible tops (assuming you have one) becoming clogged which forces the water into the interior of the car. The lowest spot is behind the front seats. On the drivers side below the seat is the Security module which if soaked could cause some problems but I'm not sure it would tie into the radio short. Loren or Tool Pants might know better.

As a last guess you might pull the radio to see that everything is tied in correctly. You will need a set of special tools to pull the radio which can be ordered online (under $5 USD). Short of this I'm out of suggestions. If you come up with the pcode for the aux/ input output please post it. By the way, as Loren indicated its not a good idea to up the fuse rating to fix a short. Good luck.

I have the p code for the aux in/out problem, it was in a previous post i applied a few days/weeks back, when i first joined, I have checked, the only water i could find anywhere in the car was in the front trunk, but its not that big of a leak, more like the hood lifted for a moment in the rain, which, the previous owner sometimes left the hood open for a moment every once in awhile, and the moisture never went away over all this time. Now I also looked back in behind the seats and they were in perfect condition, without any wetness of any kind. Now I have the porsche repair sheet that they repaired, and what im seeing from that is that the top trans died *convert* and that was replaced, also, remotecontrol head/theft unit/indication sticker-f. these are the parts repaired, apparently a few months ago the car locked everything out of it, and that was when the problems began. there was never any wetness inside the car, I called the previous owner and asked about the wetness, they told me that everything had been normal after the repairs, and they became concerned that there was a wire that had been just wrapped after the security system wihtout any acctual repairs, because of the cost from the stealership.

By the way what happens if i run it with a higher fuse in the block?

Thanks, Bryan

Bryan,

I'm out of ideas. I'm not sure if it is related to the work you had completed. The problem with using a larger fuse is that you might damage the equipment or overheat the wiring. A good web site to get the basics on fuses is http://auto.howstuffworks.com/wfc1.htm

One last thought. In the front truck did the water get as far as the stereo amp or the CD changer if you have that option. those are located at the rear (closer to the passenger compartment) of the trunk.

Other then that it sounds like a trip to the Stealership!

thanks for your help on this, the water never got back to the amp. Theres no cd changer, The water just made it a little about maybe 5 to 6 inches into the compartment on the drivers side just past the corner. it left a bit of a waterstain but nothing more, when I last spoke to the stealership they told me that it sounded like soon I would need to have the cluster replaced because of the CEL aux in/out p code. the unfortunate part is that I dont think I need it, and I've checked all of the possible lose connections, I have gotten under the dash, and into the back of the head unit. unfortunately I found no traces of lose connections. However, Thanks for all your help guys, any further information you guys want to suggest is more than welcome as I'm sure that there are more then just one boxster out there experiencing it.
