i am driving a Peugeot 2008 1.6 e-hdi 2-tronic.

I want to disable/not use the navigation of the SMEG unit but divert the GPS antenna and one radio antenna to my VDO dayton pc5200.

For that i am looking where to connect the :
12V battery (continous +)
12V accessory
0V ground

reverse gear/light
dashboard illumination (on/off)

Anyone got an idea where to connect this (on the back of the SMEG /somewhere else in the car?)

Kind regards,
