I’ve had it fitted for a few days now and it does work. Yes it is just a Bluetooth ODB2 adapter. I’ve seen zero items that cost money to use, perhaps my car has only the minimal support. I can see: How long parked and location/directions to assist return to car (if you need that help!) Parking time reminders Fuel level Odometer Selected retailer info (you can change this) Time and mileage to next service (I used an independent last time and it still has the info) Battery voltage (not useful) Functions: Find a local parking space (not live space info obviously so no better tha Google) Refuelling stats Record of trips (trips can be disabled and deleted individually) Accident alert (that may cost I’m not going to try it!) Make a service booking (gimmick) You can disable individual functions in the app if concerned about privacy. The big issue I have is that the Android app uses power even when the car is not used. 3% today and I’ve not been to the car. When used 4 times yesterday for a total of 30 miles it used a horrific 10% of the battery so I may be halting background use, losing almost all functionality and requiring running the app to get any info for later. Others are rporting high battery usage so perhaps they will rectify. If you get it, you can try it and just uninstall if you find it useless or too much of a privacy concern
I have a 2014 C-Class. I've played around with the Mercedes apps and services since I got it and can confidently say they are utter, and complete, rubbish from start to finish. Mercedes need to revamp their online offerings because, at the moment, there is absolutely nothing to recommend them. They're slow, buggy, inconsistent and limited. 'Free' is still too expensive.
Get this fitted and you'll have the service department calling you up every time you have a blown sidelight bulb or similar. The dealers make very little margin on selling cars or parts in the first place but they make a huge amount of profit on anything they can put through the service department. This device is designed to bring more work into the official service workshops, not to help the owner of the vehicle.
True, they make a half decent taxi though.
Exactly this. £5 for the adaptor, loads of free apps that will tell you all manner of metrics, OBD II problem codes, blah blah blah. Instant and average fuel consumption etc.
