I saw that program .. And I own a palm pilot.. but would the cost to purchase the program and connectors ..and any other needed accesories to operate this device exceed that of just taking it to MBz dealer or shop to diagnose and repair.. or would it be worth it to purchase for maint.. and repairs for an owner.. because after retrieving the code.. you then have to interpret and subsequently repair ..if in fact it is within the knowledge and skill to do so,,right? so what would u suggest.. bite the bullet and take it in? or buy the program and needed attatchments?
