Electronics » Connected ride cradle Quirks

Hi Folks, after going through another Nav VI, I have now installed the BMW connected ride cradle. It seems to work ok but with a couple of odd quirks. The first one is the display of the speed limit shows 1mph less than actual!! So when in a 30mph limit it displays 29 mph .....a 40 limit it shows 39 etc really odd. Has anyone else experienced this?

Next, when you look at the bikes data, Mpg, avg speed, volume in the tank etc, it is in US units !! again I have made sure both the bike and the app settings are UK units but no change. has anyone else having this issue?


Thanks

So when in a 30mph limit it displays 29 mph .....a 40 limit it shows 39 etc really odd

What are you accepting as the correct mph? your digital displai is likely bmw set, satnav is satelite set.

Most speedo readings are 'low' compared to satnav, both on my bikes or car, either with 'stand-alone' or satnav V

My bikes R1200RS, R showed alower speedometer dashboard reading than any satnav - satnav accurate but speedo has a legal setting to not 'under-show' your speed, as per regulations.

I think he's saying is that the navigation program displays what the posted speed limit is, and that display is -1mph vs actual. He's not saying the speedometer is reading low.

The TFT on the 1250 also displays the speed limit if configured and it never shows -1 vs actual posted. Sometimes it's wrong (like I've seen it show 50 when posted is 30), but I attribute that to the data.

Just to confirm my understanding for my bikes/cars speedo displays. which are bmw factory set and are electro/mechanical and run from gearbox/abs/drive shaft ouptut "who knows where?" but display the vehicle calibrated speed from wheel rotation/gearbox settings.
I have had three satnav, only one was bmw garmin (Tom-tom the others) and they always seem different to the vehicle speedometer.
The factories can never supply an accurate reading as the steel wheel/alloy etc, tyre make, pressure/tyre profile/wear/cornering lean angle reducing radius/circumference etc has to be compensated for, so all speedos, for legality are always set low so we "the genearl user" keep within the posted speed limits rather than exceding them.
Unless you had a laser guided at the ground, to get correct speed on the road, then there are too many variables for factory reliance and legal compliances worldwide.
A satnav reading over a distance can give you a more accurate reading and is why I see 30 or 40 mph on a sat nav where the speedo shows a higher speed.
Set the cruise control to 50mph in a traffic/roadworks zone and I find I am faster than some cars and my speedo shows 52/53 mph
If I set cruise to 47 mps the speedo then shows 50 mph so this is not an error, just an accuracy correction between settings.
Not saying this is the same for all systems but I think the satnav is a better guide to speed across the tarmac.

Correct, The nav knows where I am and indicates the speed limit where i'm passing. It also picks up the speed limit changes really well but displays the limit always -1 ....Can't just be me with this issue.

It's not just you. Here is BMW Motorrad Connectivity Support's respose to my bug report:

"Thank you for your e-mail. We appreciate your efforts to direct your request to us.

For the indication of the maximum permissible speed, the corresponding traffic sign in the USA was taken as a model for miles. Of course, this is not correct in every case. In Great Britain, miles are also used as a unit, but the corresponding traffic sign is the same as the one used for kilometers on the continent.

The display of the maximum permitted speed being one mile too low is in fact a rounding error caused by the app.

These two point are already on our list of possible improvement that we would like to implement in the future. However, please understand that it is not possible for us to give you a concrete date for the realization today. Thank you for understanding in this matter."

Here is the answer from BMW

Dear ATGANI,

Thank you for your e-mail. We appreciate your efforts to direct your request to us.

We are aware of the issues regarding US/UK gallons and the speed limit display. There are already tickets submitted to the responsible developers. However, please understand that we cannot tell you today if and when there might be a solution for the issue. Thank you for understanding in this matter.

Kind Regards,
Steffen Kraft

On the first issue, talk to Garmin. My 2 cents is that someone bungled the map data that tells the GPS the posted limit for the road you are on. It might be corrected by a map update. I don’t have an issue with my current map…but it’s over a year old (North America). What map are you running?

On the second, I don’t know. I know you can set units for US or Metric. I would presume it would affect all items. Also ask Garmin about this. It’s possible there’s are multiple settings in the unit but you’d not think to look for the others having dealt with one.
