Have tried on the ICE forum but not had any luck.

 

I know if you do some di-assembly it's probably on a sticker on the unit.

 

Advice on ICE was to hold down 'Setup' button for a few seconds until a menu comes up with 3 options

FM, AM and Version.....touching Version giving the required info.

 

However on my Bolero you only get FM and AM as options (2010 Yeti) The OP poster had a 2012 Model.

 

Any other way of obtaining it as not keen on taking it apart?

Either try pressing for longer or try the i/info button

Have tried for longer but will try for longer longer!!!

 

Not noticed the 'info' button ...can you please expand?

Most radios it's next to the cd slot

Not on a Bolero it isn't but thanks for trying.
