how to upgrade the NAV600 to a NAV900.

[tucpal]

yes all links still work the only function that will change is that when you want to make an outgoing call via bluetooth
you have to press the phone button on the display first and then the steering wheel phone button
incoming calls work just the same as they did stering wheel only this really is no big deal at all

but please read and follow the how to completely and correctly and follow each step one by one and you will have no problems

sd card gets removed at a certain stage of the update so no this will not affect anything at all there

speed cams are added after the 3d map update only and must also be done and followed correctly
