dash disassembly & radio antenna ???

[yamaha129]

Does anyone have a link or a breakdown of how to disassemble the 2010 dash to get to the radio antenna?

i am going to install an antenna coupler for the radio & use the stock antenna for a radio scanner.

had to disassemble the 08 for the sirius radio modulator, but the 2010 works better plugged into the aux port.

thanks for any replies.
