That’s what I use yes. I like Garmin, but the Nav units are not the best in my opinion, being slow and out of date mapping wise as soon as they are updated. The issues linking them into the TFT/phone/helmet are well documented and they are also expensive. They do have the benefit of being glove friendly, but I can live without that. Plenty of bikes gloves have screen friendly fingers now, or you can use a stylus.
I use my phone as has Google Maps, Waze and Scenic loaded into it as well as OS Maps so I can choose my mapping depending on what I am doing. The traffic is also bang on, especially from Waze. The WunderLINQ always me to navigate around the screen using the wonder wheel when I need to. By not having the Garmin unit included, it’s one less bit of kit for the flakey TFT software to deal with! It’s expensive, but so is the Nav 6.
