I also have a Honda that powers down the lighter socket when the engine is switched off. I get the 1690 screen asking if I want to shut down or stay on. The 1690 does whichever option I touch... or shuts down in 30 seconds if I make no choice.

I'm seeing some strange fuel consumption figures with my 3790 and ecoRoute HD on two vehicles.
On a 2003 Hyundai Getz, it seems to start out fairly accurate, but over time begins to show lower and lower fuel consumption.
On a 2007 Camry, again it starts out fairly accurate but over time begins to show higher and higher fuel consumption.
In each case, the values seem to change slightly each time I enter the "at the pump" details. The "at the pump" calculation is correct (as you would expect), but I then start seeing a change in the calculated real-time and trip values.
For trips to work, the Camry normally gives around 8.6 l/100km but the nuvi was showing averages around 11.5 before I reset the vehicle profile. After the reset it is again matching the actual figure. This is all under fairly similar driving conditions.
Has anyone else seen this? |

| What screens are you looking at? The fuel consumption graphs and the summary that pops up when the power to the GPS is cut? I don't find the former very readable, the latter is better but I haven't checked it for consistency. Same goes for the instant MPG reading. As long as the mileage shown in the "At the Pump" screen is correct the rest should be ok...but the fact you need to input city/highway mileage raises some questions as to how they do the math. |

| All displays seem fairly consistent. The ecoRoute Fuel Economy display, the Mileage report and the instant consumption display seem reasonable consistent, but do gradually vary from the "at the pump" update figure. The "at the pump" calculation is about what I would expect, but the nuvi calculated values seem to diverge more with each top-up where I would expect the opposite. I'm not absolutely sure as it takes a few weeks for the difference to be noticeable. I'm going to be watching it more carefully. |

Does the Ecoroute not display litres/100km when in metric mode? I just ordered one and assumed that it gives mpg for miles and l/100 km for km.
Thanks

| The display is in whatever units your nuvi is set to. |

Not sure if it's my car or the ecoRoute HD module, but the thing won't stay connected / powered on.
As soon as I connect it to my car's OBDII port, it starts flashing green (even if my key is not inserted into the car). It connects to my nuLink 1695 (sold blue light) then connects to the car (solid green light), but after awhile, the module just goes dead (no lights at all). I have to unplug from the OBDII port then plug it back in and it starts the connection process with the nuLink 1695 and car again. Then after awhile it dies again. |

| My ecoRoute HD has been rock-solid with my 1690. What does Garmin support have to say? Is your 1695 firmware updated? Done a hard reset? Assuming your car is not on the unapproved list, the pattern of failure you report should be a good indicator to tech support. |

We are using the EcoRoute HD with a 1997 Jaguar and a 2005 diesel Mercedes. The HD works reliably with the Jaguar, but function is erratic on the Mercedes.
The connector is a nightmare starting with the fact that you have to stand on your head in order to see the under the dash receptacle. The pig tail is too short, the connector doesn't have positive locking and there is no easy way to secure the unit. Resetting is required on the Mercedes and it is difficult to reach the button.
The display is very poorly designed. Screen space is wasted on the analog displays. It would be far better to have a combination of bar graphs and numeric displays. The software doesn't handle a number of important parameters. There is no easy way to switch from engine monitoring to the map.
Most of the OBD-II devices use an indirect and very inaccurate means of computing fuel flow. A far better approach is to obtain fuel flow information from a Floscan or similar sensor. Also, oil pressure, an important variable, is typically unavailable.
Finally, Garmin doesn't provide an easy means for adding third party software and their Bluetooth transmitted protocols are not industry standard. The Bluetooth device is thus not compatible with other
OBD-II software.
The ability to display diagnostic codes and to reset the dreaded engine check light are fantastic features. Garmin, unfortunately, didn't implement translation of the codes to natural language.
One possible alternative might be to use an industry standard Bluetooth OBD-II transceiver with a Magellan GPS which can be utilized with third party software. |

Modern Diesels use a lot of proprietary codes (at least I know my VW does) -- see ross-tech.com to get an idea of how much it costs to produce an OBD device and software which can do all the things you mention.

I installed the ecoRoute HD in my VW today and paired it with the 3790. All seems to be working as expected except I don't see any way to show instant MPG on the map screen. I've read that it should be an option by pressing the Arrival icon in Standard data mode and as an option available in More Data mode (as gpspassion notes above). All I can see is Average MPG using the Fuel Economy icon under Tools - ecoRoutes.
Any help would be appreciated. Thanks |

I recently did a hard reset on my 1690 after a recent map update and lost the fuel economy field even though the GPS said the HD device was connected. I deleted the connection and re-established the connection and got my fuel economy field back. Maybe that would work for you.
On the 1690, I have 4 fields on the side. Any field but the speed field can be changed to something else, the fuel economy field being one of the choices along with elevation, eta, distance remaining, etc. |

The 3790 is the same layout but there is no fuel economy field listed. The selectable items are the same whether the ecoRoute HD is active or not.
I'll try the delete the connection and reconnect to see if that helps. Thanks |

FE didn't even show as a choice after the hard reset until I deleted and re-established the HD connection. Stray electrons...~.

@Rick:
It may be because the number is too large to fit the display [grin]. As we begin hurricane preparations here, i like having 600 miles worth in the tank.
