Using v1.57, the 1 way system needs to be updated to exit from Jalan Ampang Utama to Jalan Ampang (as marked on the attached jpg and gdb files).

Turning instruction should be added / amended at this junction. My Nuvi shows the pink track turning left onto Jln Ampang but the driving instruction reads turn right (which refers to the next junction further along my route and not this junction). TQ!

Coming off the elevated highway from Ampang to connect to Jln Ampang, the map routes me to turn onto Jln Yap Kwan Seng. However, this can't be done as it means cutting across traffic and double white lines.

The correct turning should be further down at City Square / Ampang Park.

Problems with the end of the Akleh elevated highway and J Mamanda 9
The Ampang lane of the Akleh drops down to ground level and merges with Mamanda 9 Southbound North of the map position

Mamanda 9 is a dual carriageway with a couple of u turns, giving access to the Sports Planet road and allowing traffic from the Akleh to double back to Ampang point.
It is more outside of the the Akleh than underneath.
I guess that a GPS can get very confused here

Just wondering if the problem is related to elevation, would it be possible to use elevation data to determine the route as sometimes you may be on the highway above and the GPS thinks you are beneath it and vice versa. Bro Sunn, any insights ?

Standard GPS vertical accuracy is not as good as horizontal by design.
In practice elevated roads are not high enough above the terrain to reliably tell the difference

When you are on the road underneath, the signal is degraded with a lot of reflections, reducing accuracy quite a bit.
