The only gripe I have is with the clicky key sounds in the nav screens, but I'll play around with the audio files in data.zip until I'm happy.

One quick question though: What's the difference between the various speedcam alert settings (off, on, full, custom)? I think I can guess what off, full and custom are, but what about on?
You can disable the key clicks in Settings but not change the click sound. I will add to my list to have a selection of click sounds.
In the settings
Off= DIsabled
On= Alarm for Basic types and Off for advanced Types
Custom = Enable Speeccan menu and set warnings per type
Speedcams types (Basic and Advanced)
For Each Icon
Disable = No Yellow border on icon
Enabled = Yellow border on icon
Pesss the icon to change the mode. If it is disabled the settlings below the icon are meaningless.
For the settings types
Off = Disabled (same as disabled above)
Alarm = If going slower than the camera speed, no alert
If within tolerance range, a single alert will sound,
If speeding, constant warning till you pass the camera
Warning = If speeding, constant warning till you pass the camera
Reminder = Single Warning of camera, regardless of speed
A new version V3UDATE02C_beta1 is now on 4 shared
This all the same mods as V3UDATE02C_beta but the base mods have been upgraded the base code diaftia's V2.2 to 2.3.
From diaftia's release notes
* Speedcameras now display in smaller format when signpost is up so there is no overlapping on the freeway.
* clicking the signpost removes the signpost as usual and restores the speedcam to their original format.
* FINALLY fixed the problem where supressing a speedcam type would still have the distance to speedcam appear on the map
* Added a quickmenu for some system and route settings. Activate on long press of quickmenu button.
* Changes, updates and bug fixes to the split screen.
* Multipoi icon fix
This file contains only the data.zip to replace your current one. I am in the process of checking the files so let me know if you find any bugs.
Cheers
