Look, it should have been user-configurable but it is what it is. As I went through a drive-thru at a Wendy's, the Eco Start Stop was kind of nice. That extra bit of quiet really works when paying for and receiving your meal.

Sweet. Nicely done.

Cost? What do you get and how is it installed?

Thanks

170.00 brought to Car Audio shop paid 50.00 to install

Any impact on warranty to install this?

No impact on warranty .. frankly it's a EZ wired in connection..

Seriously. For ECO Mode default off, see GL X166 Forum and the various threads on the subject.

Thought I would hate the ECO mode but it doesn't bother me so much as it did initially. It would be nice if ECO on/off would default to last selected option as radio, seats, and other devices do. Also maybe programmable by type of road - should be off for freeways and maybe on for suburbs with long traffic lights.

My local streets need reprogrammed lights but that's another issues...

Don't mind it the eco mode all but understand those that don't like it. That said, I don't understand why you would pay to avoid pushing the button once every time you get in the car. Seems like a pretty simple habit to instill - foot on the brake, push start, push eco-off, done - but to each their own. I'm far more irritated by having to hold the seat memory button down for ~5 seconds every time I drive the car after my wife.

+1...That's the stupidest thing
