I've owned a Bolt for over a year so know exactly what it does/doesn't do.I've not experienced "Wahoo infrastructure"failing in that time in the UK,France or Mallorca!.....
When you've left high and dry with a dead brick because of such failures you get to question the device, it's design (software wise) and the focus of the company providing those systems.
I'm not commenting on it as a device for recording HR, cadence, calories, Strava whatevers, etc. but on it's navigation capabilities and reliability (or lack of reliability).
But I must admit I did feel a bit daft when these issues emerged as the guy in the shop advised me against the Elemnt saying they got loads back. But I ignored him and then ended-up joining that group.
The design of the system (i.e. route -> smartphone -> Wahoo Infrastructure (over internet) -> Elemnt (over internet)) did on occasions cause annoyance. At a couple of places I had no GSM coverage and ended-up having to pay for Wi-Fi (which was overpriced). And I then found that the Wi-Fi permits only a single device - yet to get the route Smartphone-> Wahoo and Wahoo->Elemnt requires both smartphone and Elemnt to have internet access. So I ended-up having to walk into town to get GSM coverage so I could use phone as a hotspot to get the Elemnt connected to the internet to get the route down from Wahoo!
I never tried it (I was not going to fork out €3 on an experiment) but I don't know how the Elemnt would handle connecting to a Wi-Fi network where you get diverted to a "landing page" where you enter a username, password agree to T&C's, etc (after connecting to the Wi-Fi, to get access beyond the Wi-Fi to the internet)
I transfer everything by Bluetooth?The only time I use Wi-Fi is when updating the unit.You need Wi-Fi/Laptop/PC to transfer files to a Garmin anyway.
On another note did you try navigating when not on the Map page?The reason I ask is that on my Edge 800/820 and my Bolt I open a route then go back to my default page and the unit(s) then prompt you when to turn etc.I found absolutely no difference in quality of the the Turn-by-turn between the Edge 820 and the Bolt.OK the Edge 820 has a colour map etc but half the battery life of the Bolt.The Bolts LEDs can also be set to "countdown" if you miss the TBT prompt for whatever reason.
