I lost the RDS details and the info button stopped doing what it did prior to the upgrade. I found that if I reinstalled an earlier version with the radio switched on and just before pressing ok to reboot the nav system, I switched off the radio by pressing the vol button and switched it back on again, then pressed OK to reboot, the info and rds were ok afterwards.
I then upgraded to the version I wanted and did exactly the same radio off / radio on and all was ok.

Not sure if this will help...but does no harm.
This does not fix the ETA issue which I have so I will get it recoded when its due for service soon.
