I just switch on Waze on my mobile, switch volume on high and place the phone on the I-Drive Screen. Works fine! Now, if you got about RM2500 to spare, you can do mirror link.
What mirror link does is to sync your I-drive & mobile phone screen together with its audio. In this way, it allows you to use Waze and watch You Tube videos on the go.
This option is available if you have deep pockets!
