Feature overload

Seduced by the adverts and the prospect of adding yet another shiny object to my collection of gadgets, I recently invested in a GPS device for my car.
It contains all of Europe, North America and the Canary Islands, as well as bluetooth capability, a 20gig harddrive, slideshow capability, mp3 playback and god knows what else.
If however i want to use my phone with it, I need to attach an external mike to the device.
I found this out the hard way when an important phonecall ticked in and the person at the other end could hear nothing despite my desperate shouting.
Secondly if I want to hear the music stored on it on the stereo, I need to run a cable from the device to the line in socket.
Adding the absolutely essential power cable means i need to have no less than 3 cables running from my windscreen if i want to use these fancy features.
Imagine the setup time, as the device absolutely needs to be put away when you leave the car for more than 5 minutes.
Needless to say I do not use it as an mp3 player or handsfree.
My wife has laughingly suggested a man-bag for my Ipod, mobile and gps.
I fear she will buy me one for christmas and force me to use it!

I do however hope to go to North America in the new year, to justify the Gigantic America map installed. Failing that the Canary Islands.
Or, at least Southern Sweden 30 miles away.....
