how to upgrade the NAV600 to a NAV900.

[havok]

Hi tupac,

I have managed to flash the firmware with the files on the first post. Only other thing I have added is the POI for cameras.
I have noticed a bit of a random bug where when I first get in the car (it's only happened 3 times so far), there is a "bong" noise as if I had left the keys in etc. - it even carried on when the car is started. If I then switch off everything and then put key back in and start the engine all is fine and stops the noise. I can only put it down to this firmware update as It has been fine up until then.

Has this been experienced by anyone else?

From reading through I understand that the firmware flash only brings my unit up to v181 - will I be ok to load the V208 firmware (which you have provided above) on to a memory stick as before (deleteing previous obviously) and then letting it upgrade the unit? I don't have to do anything special like the 80% failure originally?

I don't have any themes, just POI, so I am guessing as long as I have a backup of them then I can just proceed to flash the unit then load them back in on top?

Thanks,
Dave
