I have just read the 2018 Jazz brochure, I can't find any reference to mirror link.
This is the 2018 spec from the brochure -
♦ Honda CONNECT with CD player (7" Touchscreen
Display with: AM/FM Tuner, Internet Radio, Aha™ App
Integration and Internet Browsing*)
It also mentions this -
*Connectivity for Aha™ app (including internet radio) and for internet browsing is through WiFi tethering or mobile WiFi router. Data usage and roaming charges
may result from using applications on Honda CONNECT. We recommend you check your mobile phone subscribed package. Internet browsing function can
only be used when the car is stationary.
†Always use the recommended USB flash memory device. Some USB memory devices may not work in this audio unit.
ΔPlease ask your dealer for a list of compatible Bluetooth™ phones, pairing procedures and special feature compatibilities
It does say that DAB radio is an option, I thought they all had that.
If you expect more than this you have bought the wrong car.
