"Excellent product works flawlessly."5.0 starson by bobjs3
Pros: Tried other BT OBD2's and they would work intermittently.
ECO working perfectly for a month now. Great shoice of displays. Does not drain car batt when off, like others. reading/turning off check engine (after correcting problem) light works great.
Cons: Cord could be 6 inches longer to allow more mounting options.
Summary: Best OBD2/engine data display I have tried. I tried 3 other brands (BT to Android) and - they were unreliable and drained my batter, and their Tech help was useless.
The Garmin Eco-route HD worked perfectly the first time on three different autos I used it on. I now keep it permanently attached on my Chevy Suburban. Diagnosing and correcting check-engine lights has saved me hundreds of dollars, and paid for the gadget. I find it more convenient to have all this data integrated on my Garmin GPS than to add another app to android, although this device also gives you that option, if you prefer to go that way. I have been a fan of Garmin's high quality technology for a long time, and the addition of the Eco-Route HD just adds to my enthusiasm.
