Suzuki "Bosch" navigation?

Hi all,
I have just bought a new Suzuki Vitara, here in Australia. The built in Navigation is part of a Bosch entertainment system. But it lacks a lot of things, like school zones, speed limits and a GPS Speedo!
I have looked everywhere for hacks to install the extras, or to replace the whole Nav system (it's Linux)
Can anyone suggest or help?

Moved to Car navigation section....

Hi,
Could you please send me the web site were those zones/poi's are listed? I export my poi's with tool made for Nissan and then I put names with vloockup in Excel. I could do it for you if you need. Actually there is a lot of videos how to compile custom poi's. Replacement with another navi do not worth it- you could use build in android auto...

Hi Igniter, yes I gave up trying to "convert" Suzuki Bosch, using Android Auto Tom Tom

Bonjour,
Voilà, je recherche une mise à jour pour une Suzuki Vitara.
Pouvez-vous m'aider à trouver la mise à jour sur le site.
Merci
Cordialement
