roaming | If your display is an original Universal Display (5 inch screen with 1 card slot), then you can only update to version 4.7. Version 4.7 still can't understand the NMEA quality messages from high-precision signals, so you're out of luck unless you get a different display.
If your display is a Universal Display Plus, then you can update to v31.4. Depending on the age of the display, you might need a chip update before you can update the firmware. Your dealer will have to do the firmware update. It takes about 30 minutes and he will either have to make a service call or you'll have to take your display to the shop. I think the chip update is about $150. You can update the chip yourself or have the dealer do it. | |
