Updates fix problems and bring new features. You should check the current version and post what you find. The first post in this thread gives the button sequence to check firmware version.
I never updated mine the 3 years I had my 9.8 before upgrading to the 80.2.
If I remember correctly, on the 9.8, it was recommended that the upgrade be done by an authorized service center. since I never had any issues with the unit, I did not bother to have it done.
