DDJ SX1 compared with DDJ SX2

Hi

Ive had a DDJ SX1 since they first came out and I've got a pretty good traktor map but want to improve it. Will DDJ SX2 maps also work on DDJ SX1? I've tried one which didn't work but not sure if that was just the map i happened to find.

It seems like Pioneer have disowned the DDJ SX1 despite people like me spending £800 on them...

Thanks for any advice.
