Unfortunate but on the other hand: you have bought the absolute greatest unit from xTrons there is
Well worth the wait IMHO.
To be honest: I just bought a R75 for SWMBO so that I have an excuse to transplant my xTrons to her car and get myself the same unit you bought.
The unit will arrive and after you have installed it you'll forget the time you have waited for it (trust me!
)
