Hi i got a GPS in my 2004 mazda rx-8 and when u turn on the GPS i get a Can not read disc error not to sure of the exact words but somebody must know how to fix this? ill try to provide more info as i get my car back.

 

May have the wrong formatted disc in the drive; which one is in there?

 

Is it a legit CD? If it is a burned copy it's pretty picky on what it reads, I believe you need to burn the iso on a dual layer disc.

 

cd looks legit its called (Nav Tech) nivigation system map data dvd
North america

 

Maybe it's a bad disc, here's a link to the manual: http://foxed.ca/rx7manual/2003mazdarx8/
If I remember correctly, the section you need is in the "Entertainment" sub section of the "Bodies & Accessories" section.

 

ok i cant seem to unbuild the middle section but i have a feeling that its the DVD rom itself the prob can that be changed is there a place i can buy one online or try to detect that that is the problem. i put the disc in i hear it try to read but dosent seem to start. the GPS rights preparing info and then bomb unable to read disc. maybe it is a bad disc is there a site i can download the disc and burn it?

 

Where are you located? Maybe someone local to you can loan you a disc to try in your system to verify a bad disc. You can buy a disc from Navteq but you are looking at $199.00 for it. As far as downloading one goes, you will have to search through the threads.

 

I've successfully copied the disc. You'll have to luck out with the right recordable media, hardware and software. I tried a few newer drives and they all failed the recording. (I think it's to do with the firmware trying to do error correction when you actually want the error to be written to disk).

Before buying a new drive, try cleaning the lens with those CD's that have the brush on them. The repair should be pretty easy if something is physically broken. (Given you can take it apart and inspect the cogs/motors).

If the DVD is scratched you can try buffing it with car wax.

Also if you've improperly burned the disc (or have it upside down), it'll get the same error. Label up.
