Hi there, I have a 2018 Ford Fiesta. I’m looking to upgrade it from sync 3 to sync 3.4. The new UI looks way better. I’ve had a read through the instructions and have a few questions. I was just wondering if it was required to do any flashing using FORScan? I’m new to this and don’t feel comfortable messing with the data like that. Also if I just install sync 3.4 will the software extras remain like reverse parking sensors or would I have to flash that in after the installation has complete. I have the navigation version of sync 3 and was also looking to update the maps. I’ve heard version 3.4 requires a lot of storage. How do I know if my car has the storage requirements to hold version 3.4 with navigation and the latest maps. Also is there any what not to do’s? Don’t want to end up bricking my car.
Thanks in advance.
