Larry,
I think you fall into the same rut as most people who have used a different navigation system for a period of time. You get used to the way that particular unit handles...and using certain functions of that unit. I've had about 3 different nav units (The e90 navi will be my 4th) and each have had their positives and negatives. Each time, I found myself comparing features and wishing that each nav did something different. After a while, I became accustomed to each unit and used that unit as intended without a hitch.
I think your suffering from the same thing I went through....withdrawls and comparisons to your "old" system. Each system will do things differently...it may seem less efficient than your old way, only because humans as a species do not welcome change.
Good luck getting used to the new nav...I think you'll enjoy it if you give it a chance.
