Hi, The wierd thing is that I recoded 2 x Mk4 navs last weekend. Both of them worked perfectly, arrival time was not lost. But I recall I didn't tick 'Show arrival time'.

They were fitted to E39s with 4:3 displays

But to help people I have made a test version of NavCoder, where all 8 bits (0 to 7) can be set, to see if there are some undocumented settings that influence arrival time.

I cannot see anywhere where I can upload files on this forum, so I have it on the bimmerboard forum:

Actually I just see that the users on bimmerboard found the solution - you do NOT set 'Show arrival time' on the E39 with Mk4. Then everything is fine.

I actually think that the 'Show Arrival Time' is maybe only for cars made up to 09/03 - ie: for those fitted with Mk1, Mk2 or Mk3 nav.
Maybe "PU 09/03" means "production until 09/03"

So for Mk4 nav do NOT select 'Show arrival time', then everything works
