Hi My 2006 Presara has, for the last couple of months, developed a frequent problem. All the controls connected to the screen (Satnav, telephone, audio, menu dest, tuner etc) freeze. When I press anything connected to the screen there is an approx 20 second delay, if not more, until it actions the selection. For example, if I am using the satnav to get from A to B and I want to change radio stations, both the steering wheel buttons (Mode and the Up and Down arrows) will not perform until at least approx 20 seconds after pressing them. The sat naf screen sort of works still. The red positioning marker still moves and the map still moves showing your location. However the information box in the top right hand corner (which shows, for example, turn left in 5km's) becomes just a white blank box. All these freezes start working again when the system feels like it and will no doubt start freezing again not long after. It just keeps doing it. This also happens with anything else sonnected to the screen as mentioned above. The controls on the right hand side of the steering wheel (related to the air con) work fine and all the air con controls on the dash are fine. Thankfully, my cruise control works ok. Has anyone had a similar issue? Cheers Budgoi
