Only had our Knaus Sun TI for a year and this post may well be teaching granny to suck eggs. But just in case anyone is still struggling with the annoying sat nav, here's what I discovered by chance.
There is only one volume control and the unit was designed so you can't turn off the radio. So you have to turn the radio volume right down if you don't want it on, but what about the volume of the sat nav instructions? It seemed to have a life of its own, sometimes loud, sometimes quiet. It drove me crazy.
I asked the Fiat dealer when we went in for a service and he told me the sat nav volume was set at a constant volume (which I know to be untrue).
Finally I cracked it. There are two volumes. One when the radio is on and another when the sat nav is on. So wait for the sat nav instructions to speak and then adjust the volume then. You have to be quick though if the instructions are short. The sat nav then remembers that volume. When the radio is on you can turn that volume right down or not, but it won't affect the saved sat nav volume. Simples
