I have Carplay and Android auto on my Honda that can be controlled by the left hand switch cluster, and still prefer my Garmin after much experimentation. If I wasn't going to use a Garmin I'd use MRA or OSMand for navigation on a cheap waterproof phone with downloaded maps. Connecting the phone to the Honda screen via a cable and making the relevant Bluetooth connections and waiting for it all to boot up is additional and unnecessary faff compared to switching on a dedicated Sat Nav.
That said my Nav 4 and my 340 and 390 Zumo's that I use on my 1150 basically follow any route made in Basecamp. I suspect the routing logic built into those units and basecamp itself are the same having been developed at the same time. The XT's logic I suspect was designed for a car specifically to stop people ending up on narrow country roads or dirt tracks when "Fastest time" was selected and therefore the unit favours faster roads. This means that if you leave gaps in the amount of shaping points you enter in a Basecamp route the unit will recalculate it and head for faster roads even if involves a large detour and a slower overall time......and some frustration until you work out what is happening.
Using the XT I now do four things that I wouldn't have necessarily done with the old units
1. I put a shaping point on every road I want to be on and use more shaping points than I previously would have if planning routes in basecamp or increasingly MRA routeplanner
2. Always make a track and display the track and the route on the device so that I can spot any deviation(s).
3. Have recalculation on prompted rather than automatic and use it sparingly
4. Any route I'm using gets saved as an "Active Route" to avoid any issues with repeated u-turns if I have used recalculation at some point in the route.
Sounds like a faff but its a workflow thing really and turns the XT into a very reliable and competent unit (and does not take much more time)
Oh and I've just ordered the AA road maps sheets 7,8 and 9 the 3 miles to the inch series.......everything has its place.
