Easy to fit and a worthwhile (if somewhat expensive) modification to make to any PRHT MX-5.
The unit comes ready to fit, although you are strongly recommended to download the set-up software and check for available firmware updates (some features only became available on later versions) before fitting. You can also use the software to change the available settings and enable optional features.
Fitting is straightforward (the downloadable instructions are quite clear and easy to follow). The only slightly awkward bit is disconnecting one of the wiring connectors on the car (behind the passenger seat). You need to be able to apply firm pressure to a release clip while simultaneously pulling the connector apart. I found a couple of flat screwdrivers useful here - a thin one to press the clip and a broader one to start prising the connector apart.
Once fitted, you can enjoy the freedom of being able to open/close the roof without having to come to a full stop (and remain stopped while the roof goes through its motions). The roof will also continue to open/close without you having to hold your finger on the buttons. You can also set the unit to allow one-touch opening (just release the roof clamp and the roof opens all by itself).
A word of caution though (as mentioned by others): It is possible to set the unit to allow operation while the car is moving at up to 40mph. This is a bit too fast really - especially as once the process has started it will continue even if you subsequently accelerate to a much higher speed while the roof is moving. I would recommend setting the speed parameter to 25mph or so to be on the safe side.
If you have a laptop computer, the settings can be changed even while the unit is installed in the car - just take the laptop to the car and plug in the (provided) USB cable. Even if you don't have a laptop, you can still change the settings using the dash mounted control buttons - full instructions are included in the downloaded manual.
