I have a Garmin GPS in my car now. Originally, I purchased the unit solely for its usefulness as a GPS.

About a week ago, I discovered the EcoRoute function of the Garmin.

It is useful, but I am somewhat skeptical of its accuracy and thus, the extent of its usefulness.

Being that I've never used a Scanguage I, II, or Escanguage, I don't really know any other form of instrumentation.

I would think that these units would be more accurate, being that they are essentially plugged into your car's computer. However, I have been wrong before.

A)How do the EcoRoute and Scanguage compare?

B) Is it worth purchasing another unit considering the cost? (I'll still have to have a GPS!)

C) If the scanguage is considered to be better, how?


Thanks
