You do need to do the EL2 overlay thing here as well just like the other 
models have it.

Is it a 2-speaker variant (no front tweeters)? Or is that only on the

If so, the &left_tweeter &right_tweeter nodes should also be deleted 
with /delete-node/.

Also could you confirm if there's actually no touchscreen?
