I have been looking at trying leetlauncher with the new maps but i was wondering how well the new maps work with the avic software. Does the song title still show up in the corner and does it still show the current time in the top right? Will incoming calls still work correctly? And does this make the unit take longer to boot up? And what maps do people seem to like the most? Any help would be great just wondering if i should give this a go or not.

I tried it, looks nice but has too many flaws for my taste. No Bluetooth, various memory error messages etc. It is an amazing idea, don't get me wrong, but it is a work in progress. Best thing about it is that it is on an SD card hence you don't mess with the system itself. I will def. stay tuned and give it another try after the next update!

I also noticed it overrides some of the settings (like sounds settings) made in the AVIC shell.

After running the AVIC shell itself you need to re set things.
