how to upgrade the NAV600 to a NAV900.

[Chrisoldinho]

Hi guys, looking for a bit of advice.

Upgraded to Navi 900 fine, 3d maps, poi etc. I then looked at this thread again and noticed I would likely be running v181 as I simply flashed the original files in this thread.

I downloaded v208, extracted the dnl and put it on a USB. Updated fine, but now I seem to have lost 3d maps, it's basically as if the update has reverted it back to a Navi 600. The only thing I may have done wrong, was I left the SD card in whilst updating to v208, i'm not sure if I should have taken this out?

Anyway, to irritate me further I thought i'd just start again following the original steps, however I now find that after I initially insert the USB the update just works and it never goes into boot loader mode. As a consequence when the Nav reboots i'm stuck with just 2d maps and in effect a Navi 600.

My ideal is obviously to be running the latest v208 with 3d maps (navi 900), what do you suggest to get me back going?

Thanks,
Chris.
