Get the latest Sync features on your sync 3 system including the latest navigation maps - all on one plug and play USB memory stick.

Please note: When ordering you must tell us your current sync version number. You can find this in settings/About. We will need to know software version and build numbers. Failure to provide accurate numbers could damage your system.
We will also need to know if you have navigation fitted and your current map version. Please send this information via the contact us page. Failure to provide this information will delay your order.
