Why can't Boyd listen to me like his GPS system?

Last month, we had spent considerable time on the road traveling between our children that all happen to live in different states at this time. Basically, we really do enjoy just getting in the car and taking off without too many cares. (Like whether or not to bring our dog Katie with us) . We often just on a whim will get up some day, and decide to drive somewhere, anywhere~.
But, there have been a few glitches along the way that have started causing some "friction" between Boyd and I. The basic problem is that since my husband is of the male gender, he does not have the ability to stop and ask directions. So, in the midst of our fun and spur-of-the-moments travels, we often find ourselves arguing about which turn off we were to take, and what lane we should be in, and so on and so on.
So, as we are planning many more fun and spontaneous trips, we decided that it might be a really good idea to invest in a GPS. As we all know, I think it is genetic breeding that makes it impossible for men to stop and ask for directions. Although, I am sure he can point out several occasions when I have led us in the wrong direction also! Rare, but true.
The real problem I am encountering now is that the woman that speaks on the GPS system has this beautiful hypnotic angelic voice (according to Boyd). She never nags him, and she is always right. Oh, how I would love to have the same voice programed to accomplish that list I have waiting for him at home! Wouldn't that be great! Oh, well, for now, maybe I can practice training my voice and when he is asleep subconsciously put thoughts in his head.
Well, for now at least I do trust that he is happy with his new voice activated GPS system. And my nagging while he is driving is completely gone! Although, I do have to admit I am the one that programs it!
So, for any of you that don't have a GPS system for your traveling, I do highly recommend one. But, I am still awaiting the home version that will tell him what to do in the same angelic voice. Do you really think that will work?
But, for any of you that watched a particular episode of ER a few weeks ago, you will get a laugh out of this. A couple using their GPS system told them to drive straight in to a lake. And so, they did! They could see the lake, but the GPS system kept telling them to drive forward. They had refused to believe that wrong instructions had been given. Needless to say, we plan on using common sense with this. We wouldn't want our new little assisting angel to lead us astray!
