UK Sat Nav Woes

I'm just back from a weekend down in deepest Devon. As always, the car was a joy, eating the miles. However, the satnav is driving me mad.

It's German efficiency seems to insist if I can save 0.2 of a mile by taking a farm track that isn't a road at all, lined with scratchy hedges and low rock walls designed purely to destroy my alloys, it will. The number of times I had to negotiate what was basically a walking path, slowly creeping around a 90 degree turn whilst a mad Devonian in a Transit barrels towards me at 60MPH was beyond ridiculous.

I cannot seem to find a setting that allows me to 'avoid roads that are not roads.' Instead, I just ignored it every time it tried to send me down a mountain bike track, when I am already on a clearly marked B road.

I used to live down there and don't remember it being this bad in previous BMWs. Am I missing a setting somwhere to make it behave sensibly?

Set to fastest route as opposed to shortest?

First BMW for me and I have already dropped the sat-nav in favour of either Apple Maps or Google, but this does assume you have an iPhone.

I can't understand the routes the SatNav suggests, for all my journeys it hasn't found the way I go once, but using Apple/Google they do.

I only use it now to tie in the Hybrid Eco Pro mode and a I know where I am going!

You'd think fastest would be the best to set to to avoid the piddly small country roads.
Efficient would maybe however favour the A and B roads. Who knows?

I think the car just likes to wind me up.

ďLetís see what he does when I head for this 90 degree bend towards a wooden bridge with holes in itĒ.

I do, but just donít like CarPlay. Feels a bit basic somehow but might compare the routing via Googlemaps! Good shout

I was going across to Aberdeen and due to an accident, I reluctantly decided to follow the 'suggested' Sat Nav route around it. We realised it was getting a bit out of the way and was pleased when we were directed back in what appeared the right direction.... until it was clear we were heading for a farmyard. What the Sat Nav didn't know, the 'track' from the other side of the farmyard, to the main road, wasn't suitable for traffic. Tractors maybe, but not cars.

I feel your pain, took me down this road (called a footpath where I'm from) at 10:30 at night right up near Snowdon!!

My past two cars (Audi) have had the same issue with their dodgy maps.

Come off this 50mph dual carriageway to take this "shortcut" which is essentially a dirt road, only to rejoin the same damn dual carriageway. Time lost not saved there!

I was hoping my soon to be built 3-Series would be an improvement. I'll be sticking with waze then!

I bet BMW and Audi buy their mapping data and software from the same supplier!

I heard words from the Mrs I'd never heard before, but to be fair, she does think there's a serial killer around every bend on a narrow, unlit road in the dark, so this place certainly got her spooked!!

Hehe could to see bmw nav is as good as ever. I never use it unless local and always stick to waze via android auto. I think my favourite was when my f31 told me to come off a motorway junction only to go round the roundabout and get straight back on again for no apparent reason.

Pretty sure the mapping data and traffic info is supplied by TomTom, which is high quality.

It's the garbage bmw nav routing engine that is the issue. Always has been with bmw nav.

I have TomTom in CarPlay and idrive nav running simultaneously, and TomTom gets the optimum route the majority of the time whereas idrive is usually different and slower.

As BMW use HERE Technology for their Safety camera data, then maybe their mapping data comes from there also? If they used TomTom maps then surely they would have taken their routing software as well?

Maybe they have now they are using the online maps for newer i-step.

This was announced back in 2018: https://www.fleetnews.co.uk/news/man...bmw-group-cars

A little confusing as I'm not sure how they can provide online routes if they don't also provide the local maps.
The 2 nav systems definitely don't offer the same routes in my car, although I can see the traffic status updating within a few minutes of each other with the same data
