While it isn't impossible, we do advise against it. In order to get both adapters up and running, you would need to use an OBD splitter. Using a splitter can have mixed results, especially in providing inaccurate data. Also, using a splitter with Automatic can cause issues with Crash Alert and we recommend that users turn it off. For more regarding this matter, please see this FAQ.
You may also want to check with your insurance provider given their needs in this situation.
Thank you for the quick reply, Jeff. It seems like this is something that may need to be solved sooner rather than later, given that many insurance companies are moving this direction and many of their customers (like myself) value the discounts the device provides. In my family's case, the discount totals nearly $150/year, so it's not insignificant. And while i would love to have the benefits that an Automatic provides, those benefits can't really compete with $150 of recurring annual discounts. Thoughts?
Thanks for getting back, Kevin. We apologize for the inconvenience of the situation.
We don't really support the use of an OBD splitter because it has shown less accurate results because the adapter isn't directly connected into the OBD-II port. It also depends on the information that your insurance company (or any other OBD device) would need when connected. If requiring the same data, you will likely see less accurate results than when the adapter is plugged in alone. This isn't a limitation of Automatic, but rather the capabilities of OBD.
For those reasons, that is why I suggested also asking your insurance company before using a splitter as they may advise/wish against it.
You are more than welcome to give it a try, but again, we do advise against it.
