Went to see Craigyb to sort out my RNS-E coding on Saturday (thanks Craig - top man ). He mentioned that there is a known issue with SW 0550 that causes the unit to crash/freeze when certain key combinations are used. I found this interesting as it had happened to me a few times; the unit locks completely and won't even reset using the on/off switch reset procedure. It only clears when the ignition has been left switched off for a while.
I wondered whether anyone has had the same problem? Craig says there is a new software update that fixes things (SW 0600). Has anyone with this had any "crashes" since installing it?
