Downgrading firmware on iPOD nano 3G 4GB

[JustJules]

I have made the stupid mistake of allowing iTunes to update my nano to firmware 1.1.3, now it will no longer link to my Alpine car stereo. I have trawled the web and seen other with a similar issue. It seems I need to downgrade to version 1.1.1 and all will be well. I have downloaded

iPhone1,1_1.1.1_3A109a_Restore.ipsw
iPod1,1_1.1.1_3A110a_Restore.ipsw

both of which fail as being incompatible. In desperation I downloaded

iPod_26.1.0.3.ipsw
iPod_24.1.0.2.ipsw

again, both fail for the same reason, incompatible. Any help anyone can give me to get me out of this mess would be appreciated!

Well downloading iPod touch OS and iPhone OS won't help.

Neve mind. I provided you the wrong link. I can't find 1.1.1, sorry. If you have the computer that 1.1.1 was downloaded onto, it's still tere. I will help you find it if you have downloaded/upgraded to 1.1.1. But that may have been the Original shipping OS, and you may not have ever restored. Sorry.

Thanks for trying.

no I can't find 1.1.1 either, going back further should work though as long as it is 1.1.1 or earlier, but as you can see I am having very little success so far.
