This option is for customers with a Mk3 Focus ST and wish to upgrade to MR300 using an mTune, and who fall into one of the following three categories:

1. MP275 customers who have all the required hardware installed for MR300 but require an mTune and MR300 calibration.
2. MT275 customers who have all the required MR300 hardware (including an mTune) but require an in-field firmware update to their existing handset.
   In-field firmware updates are facilitated via a bespoke upgrade key. Once ordered we will send you steps to follow in order for you to provide us with your specific mTune serial number. A key will then be generated and sent to you which will enable you to update your mTune's firmware using the AP Manager software.
3. Customers running all the required MR300 hardware but using standard software, requiring mTune with MR300 calibration.
