ANV - yes I think we all appreciate the fact that the forum allows this discussion without the posts being pulled or censored....and for this I thank you.
Also must (at least for me ) thank W&S for speedy repairs.
Equally, I believe that no-one here is wanting to run down the reputation of what is after all a marvellous piece of equipment.
Additionally , I agree with the point you are making that the fault rate is in fact very low when compared to such as Xbox and others .
However-I believe the point being missed here is that even 1 in 500 going wrong is more than either AirNav or the customers want to see....and so any reasoned discussion that may seek to establish the causes of failure must surely be beneficial to all.
I was not questioning your (the company that is) level of QC - rather suggesting the possibility that of possibly those who supply the components - a thing over which AN may have little direct control- may be where the root cause of SAW filter problems lay.
Anyway - hopefully - not too many more users will suffer the LOS that has affected a few of us...and we can all get on with enjoying using the gear.
:)
