If your Tuner's Screen says Detecting Memory... There is really nothing you can do on your own. You will need to send it to SCT to have them fix it. This error is almost always caused by Dropping or Being Rough with your Tuner. These things are expensive and need to be treated with the same respect as you would a laptop. If you need anything from MPT, let us know. We will do everything we can for you. SCT Tech Support's number is: 866-927-6298.
