Yes there is but you do need to tweek the system with 3rd party software.
The following link to a US Spider owner's blog (not mine) will show you how to make a number of changes, some won't apply to you, some will be country specific.
The only two I've made are the one you want to make re driving and not being able to use the touchscreen (whoever came up with that 'safety feature'? twiddling that knob has to be at least as distracting) and removing that flippin' warning screen when you switch on.
You can make all sorts of changes; colours, new features etc etc.
Edit: link was supposed to go here but can't as a new member so google 21st century fiat 124 spider or look up ameridan on the 124spider forum.
There are plenty of disclaimers and declarations of the risks of monkeying about at this level so all at your own risk. DO check your firmware version before doing anything and read ameridan's instructions right through before doing anything.
