Amazing beautiful mountains in Switzerland! 
Like Mike I have tons of mountain flying time and have found GPS, especially the TAWS function, a valuable asset in that environment. Unlike Mike, none of mine is rotary wing (insert liittle sneering rotar-head) so I've learned that my options are fewer and I need every tool and discipline I can bring to bear to maximize safety. That's why I question your statement on GPS. 
Perhaps something was lost in translation...........
I see I wrote the last message too fast and any sense got lost, actually, sorry!
It's an idea/a problem I've since the aircraft I use was equipped with GPS, I was not speaking generally
The point is that I’ve noticed that when flying with GPS I tend to question the correctness of the instrument and always think it could be wrong (I think that it is a problem that comes from the fact that I used GPS to travel all around Scotland by car and once got lost since it lost the satellites and did not hear the messages and consequently got lost with it, discovering the fact 10 minutes later, when it caught up with satellites again…). As soon as I begin questioning too much its correctness (and it always happens), I have to stop using it, since I feel like flying “unsafe” and just completely revert to the use of my map, my watch and my FP, switching the instrument's map off. On the Alps this feeling comes just in a matter of seconds. I tend to say myself “maybe it won’t send me in the right pass...what if it sends me in the valley before? what if he has lost the satellites and is saying nothing?”. Before using GPS I never had this feeling but since I began using it, I felt like I had to trust an instrument I’m unable to trust and this fact creates confusion. I probably approach the GPS in the wrong way, but it seems to me that it gives me a certain degree of uncertainty that I usually do not have.....Any idea?
on the other topic, I think we Swiss are quite accustomed about flying in the Alps and I get bored flying in northern Italy for example, where there is a big big plain and the panorama never changes. but about wind you must be careful on flight preparation. it could be that you have to cross a too windy zone or it could happen that on the southern part weather is beautiful and on the northern part of the alps it is not, but I never encountered any particular problem, but visibility because of which I had to go back (ex. layer of clouds covering the pass, no contact to the ground). Wind gust happens, but - once again - I never had any difficult experience.
