OK, reading a little more I hear about @EXEC. I'm still trying to find a post which explains it all. I see it's not in the riocar FAQ ?

Reading further about "literal site exec" so I gave that a go and I got the error similar to this post:

http://empegbbs.com/ubbthreads.php/topics/275901

But I've double checked the path to the app is correct. It's in /programs0/empeg-wideband which is what I'm trying to call.

I've put the app up here: http://www.nominous.com/empeg-wideband if someone could please verify that it's working ok ?

It's the complied version of the Innovate wideband reader/display source which was posted quite a while ago.
