I've just ordered HAWKEye V4 as I got tired of waiting for the new Nanocom.
V4 does TD5 and V8, autobox, air suspension abs etc etc.
Have a look here and download the User Manual, that'll give you the full picture.
I boutgh mine for £257.
I particularly like the fact that all LR products are loaded, so if/when I buy a different car, DIII for instance, I can buy an unlock code and then the same bit of kit will do my current car and any future purchases.
HAWKEye arrives early next week, fingers tapping noise.........................
Cheers
Dave
