does it use Google maps with your phone or garmin ?
No.
It uses BMW’s bespoke in-house, Connected app. This runs on a suitable modern smart phone. The TFT displays what is on the phone, down two separate channels:
A. The map comes across, via the bike’s own local wi-fi channel.
B. The route comes across, via Bluetooth.
The system works reasonably well, but it’s not without its quirks.
As the app is reasonably power hungry, you’ll probably need to power the phone. Depending on how large the phone is and / or the size of any case the phone might be in, you can power the phone by placing it the bike’s cubbyhole on top of the dashboard. But:
A. You’ll need a very short USB C lead to connect your phone. The USB C end connects (somewhat awkwardly) to the bike, be sure that the lead then ends with the correct plug for your phone.
B. It’s can be a fiddle, putting the phone in, as touching the screen with your fingers can close the app.
C. If the app stops running, you may well have to take the phone out of the cubbyhole to start again.
D. You might well have to set your phone not to go to sleep.
I had to buy a secondhand sacrificial Android phone to get around some of these problems.
I have my 1600 set-up so that I can run:
1. The Connected app on a Samsung Android phone, either in the cubbyhole or sitting in a powered tank bag. The route is displayed on the TFT screen.
2. An iPhone, on a Peak Design mount, the phone powered by the bike. This I have running MyRoute’s Navigation app or I can run any other navigation app I fancy. I can also mount / power my Android phone here too, if I want to. I can then either run BMW’s Connected app on it, or run the MyRoute Navigation app on it. You cannot (as yet at least) display the MyRoute Navigstion app on the bike’s TFT screen. Whether someone will come up with a box of widgets, enabling the TFT to display third party app’s, I gave no idea. I guess it should be possible.
3. A Garmin XT, powered by the bike, mounted on a stem, bolted into the steering column. I think you could well mount a Chigee the same way.
Here’s all three in action, each running the same route.
All three can run simultaneously and independently of each other. Likewise, I can (if I want to) have voice instructions from any two, coming into my helmet. I change the default voices so that I can tell which of the two devices is talking to me.
Which is best? Like gloves and helmets, everyone will have their favourite. I pretty much know how all three work and understand their quirks, foibles, triumphs and failures. Try all three and chose the one you like best.
