I think a stand alone sat nav (currently) will always be better than the Connected app navigation. For different reasons. For example. Vibrations, waterproofing, Having to take the phone out of the cradle to take a photo. Constant charging, clarity in bright or direct sunlight, device security........etc etc
I still use the connected app, just not for navigating. The maps are downloaded to give me speed etc on the TFT dash.
I don't miss the function of the selection wheel on the handlebar, as It was very rare I actually used it. The XT touch screen is good, I've never had any issues wearing gloves.
Im looking at the new K1600 , possible purchase one in March, that or the RT ? and Ill use the onboard navigation.
They all have their merits and demerits, that’s for sure.
The 2022 1600 will have the large TFT screen, as does the RT. Both have lost the cubbyhole thing where the Navigator device used to sit. To use the XT (or any standalone GPS device) on either, you’ll need to use a cradle of some sort. Of course that is not impossible to create, just as bods mount all sorts of gubbinry to their bikes, especially Americans.
