I use a Garmin 1030 + and varia rear light/radar with Wahoo cadence sensors on two different bikes. Each bike has its own profile mainly because the roadie has Ultegra di2 and I like knowing which gear I’m in and I have different screen setups for each bike.
i started with a Wahoo head unit but found it confusing and the map display woeful in comparison. I suspect they are similar now, but I use Garmin on my motorcycle so have become biased in that direction. BMW & Ducati have their own built in sat nav’s, both of which I have tried but gave up on and retrofitted the Garmin XT 2.
There is a lot of talk on motorcycle forums of people moving over to the cheap mainly Chinese units that are more like a modern cars units with Apple CarPlay, Waze and other programmes built in.
like choosing tyres you have to make your own decision, the biggest in my opinion is to have a head unit and save your phone For comms.
