Stylish however...

Easy fitment. Wiring is confusing and needed to install adapter for regional use ie: not American. Aircon wiring has delays.

installed in JDM model

I installed this into a JDM RH drive base model RX8. Happy with the shipping time frame. I didn't really want the matte black, make sure you're ordering the HG (high gloss) if that is what you want
Make sure you follow ALL of the instructions & you wont have any problems with the display & heater controls. Slight delay in the heater & fan controls compared to the OE. DIY is pretty easy except for the length of the wiring loom can be difficult to unplug & trying to stuff it all back in.
Overal a 4/5 due to the heater & fan delay

Overall, I would give this a solid "decent" rating. After 6 months of use,

PROS:
-rare fit for RX8
-enables mod/customization of top scrolling display
-keeps a/c functionality (somewhat, see cons)
CONS:
-time does not function correctly (lags), and is extremely difficult to set
-a/c button functionality as well as hazard light functionality is limited due to tight fitment/sticking of buttons
-cost is WAY too high for what you get.

This being said, since the stock BOSE head unit is a beast to replace, it does the job, and actually works.
