If you already have a Shift-P2 and would like to use the additional P2+ features, you can upgrade by purchasing the unlock code.
The unlock code is unique to your Shift-P2 unit. When ordering, please send Ecliptech your Shift-P2 units serial number. You can find it in the menu, System –> Product Info. We will send your unlock code as soon as we can. You can then enter it via the menu System –> Feature Unlock. Once entered, it is permanently unlocked with all the Shift-P2+ features.
