Carman 0.7 is available for N800 and N810 with the OS2008. But you can always install Carman 0.6 if you wish.
OBD stands for On Board Diagnostics, a standard interface used on automobiles to monitor some components, detect malfunction and store the information in the vehicle's on-board computer. The latest version, OBD2, is now a worldwide standard.
The easiest way to find out is asking your car manufacturer. What we can tell for sure is that every car built in the United States after 1996 are OBD2 compliant and that 2001 or newer models sold in the European Union are also OBD2 vehicles. Sometimes, cars that are OBD2 compliant have a label on the underside of the hood identifying them as such. The OBD2 connector should be located under the dash. Most of the times, it's on the driver's side, but that's not a rule.
To connect Carman to the OBD2 you will need a Scan Tool, which is the device that determines the proper protocol to communicate with the car computer network. It's not a precept but we advise you to use scan tools that already supports Bluetooth (devices names in the next answer). In case you don't, you can have a Serial to Bluetooth adapter that supports the Serial Port Profile (SPP). So far, we've only tested Carman with the Firefly serial adapter, but any adapter that supports SSP (Bluetooth Serial Port Profile) should work. Once you have the Scan Tool, you plug it into the OBD2 connector in your car. Start Carman and on the main menu, select Options > Configure OBD2. And there it is, you're ready to go.
Yes and No. Yes if you want to enjoy all the features that Carman can provide, including trip-track data and the info-sharing service that will allow you to share data with your pals. And No if checking your car performance, regardless of the trip you're doing, is quite enough for you.
Carman has been designed to support many map services, but due to license restrictions we could not release them included on the installation package. Learn here how to add those services.
The response delay from OBD is a combination of two factors: the scan tool and the Electronic Control Unit (ECU) of your car. Consider something between 200 milliseconds and 2 seconds delay for each sensor. Older cars may even take a little longer.
Any GPS receiver calculates its position by timing the signals sent by the constellation of GPS satellites and usually it takes four satellites to get a full position. So if the sky above you is cloudy or if you're near tall buildings or trees, your GPS receiver might take a long time trying to fix its position. Once fixed, the GPS receiver usually sends data once a second.
No worry here. Carman has been programmed to automatically save every trip you start, despite battery fails and OBD or GPS disconnection problems.
Due to some data processing limits, Carman can only save a single trip with a maximum of 10 hours. But we are working on extending that time.
There is a great chance that either you or your friend forgot to check all the requirements needed to use that feature.
