Hi Guys,

It is a Clarion with 2 sets of model numbers. It is from a Mazda MX-5

PT-2880Q

I have taken dump from 24C02 eeprom but can't seem to locate the code.

Now you've got a couple of error tries, read again and post new dump :)

(Not normally encrypted but code is usually on the last line on this model)

[Julesd]

Thanks.
These are three dumps, you can se changes around middle.

Cheers,

Can you try 1349

I can see 4913 0r 1349 as a possibility cheers

Thanks again Guys, but still showing error.
I tried these earlier got error then powered down for 5 mins then set came on saying "code".
Don't know what happened. It is still "AutoM" + "6" to enter code isn't it?

Yes Jules, usual "Auto M" & "6" to bring up code window

(Another option to try is 3194)

You're definitely entering the code mate because the counter and checksum are going up.

The code should be 4913 so something is wrong.

Put this dump in and see if it changes things mate.....

Hi Guys, I have tried Kierans dump and radio is working. Thanks Kieran.
My dump is very similar but slightly different data on code line.
Am I OK just to change code on this?

Cheers,
Jules.

[KierAn20]

Change that whole line mate because it has crc at the end of it - or i will calculate you a new crc if youd prefer to just change code.

[Julesd]

Thanks Kieran, Can you give me a new random code please? That would be great.
