I'm currently running My Skoda and Connect Lite on my Karoq built in the July to November 2018 period. I have an Android phone, I use something called Hotspot Automatic that creates a hotspot when my phone connects to the cars bluetooth and the car uses this for the navigation traffic information and the other limited bits like weather and news on the Amundsmen infotainment unit.
Using My Skoda, I don't have to connect with a usb, it seems to connect to the car via the wifi hotspot but I do have to start the My Skoda app and go into Logbook if I want a trip recorded. It then sits there telling me not to close the window if I want the trip recorded. As it takes my phone and the car a hundred yards to get the wifi hot spot activated and the car connected to the internet the journeys start recording a short distance from home.
Using Connect Lite, this connects using the bluetooth dongle, it's automatic, I don't have to start the Connect Lite app, it connects as soon as the phone connects to bluetooth which is almost instant.
On a recent jouney, My Skoda says it was 19 miles, my average rpm was 1668 rpm, my average speed was 9 mph and it took 40 minutes (19 miles in 2/rds of an hour was 28 mph when I went to school). Efficiency was 78%.
There's a few bits of info on the map, highest rpm 4122 rpm. Maximum speed 15 mph (totally wrong) Also some other info about left and right lateral acceleration (0.3g), not sure if that's the car telling me or if it's using my phone.
Some of the information looks decidedly wrong.
Connect Lite agrees 19miles, average speed was 30mph, max speed 55 mph. duration 41 minutes. Fuel cost £2.Exhaust gas temp 673.6 degrees C, oil temperature 41.1 C (I suspect that might be an average didn't check). My efficiency taking everything into account was 93%. I should soon have enough points to add coolant and Intake air temperature, but a while to go before I get to see Throttle Valve position. The map has little red lines which I suspect is when I was accelerating.
As Connect Lite is completely automatic and seems to offer more accurate information (it does come from the cars OBD port) of the two it seems the winner and if you're into apps worth a fiver for the bluetooth sender unit
Neither allow me to see the Digital Service History though which was a feature of the app My Skoda replaced.
Both apps no doubt send loads of information back to VAG but Connect Lite probably a lot more as it's in touch with the cars electronics via the EBD, just like in a plane though I don't suppose there's a technician watching the performance like there is for Rolls Royce aero engines.
