After flashing Diablo, the Nokia LD-3W won't be seen by the N800 if I run it from the old OS on the SD (dual booted). Map will refuse to see the LD-3W. But strangely map can be run from flash.

I have deleted/paired back the LD-3W but it looks like map can not be run from the old OS anymore. Does anyone have the same problem?

I paired mine just fine after restoring.

Mine works fine too, but I'm not running from SD. It could be a kernel incompatibility between the two OS versions (IIRC you boot the kernel in the on-board flash even when running with SD rootfs) - does bluetooth in general work reliably on the old OS now?

Bluetooth works very reliably on 51-3, my old OS. (remember to re-name devices with no spaces in between! Like "Nokia LD-3W" to "LD-3W" and such!)

One strange thing is that after flashing Diablo and then booting the image from SD, I could not see the OS and version from "About product" in "Control Panel" anymore. Weird!

Added: MAP is fine with Diablo. I was asking about MAP and old OS. I am downloading new maps...... I can live with running MAP on Diablo !

Also, I now know how to fix the problem. While you are in MAP, delete the LD-3W in bluetooth device list. MAP then will try to re-connect and you can pair the LD-3W at that time. MAP will be OK after that.
