whats your software on your x-15? you can try a soft and hard reset.

Lowrance Reset Procedures
This works with most newer LMS and LCX units, I have a complete list in pdf format if you want a copy just send me an email or go to Lowrance website and type in Lowrance Resets in the search field.
This reset usually clears up missing pages and menu items, it reorganizes the software when a problem occurs. It may correct gps connectivity problems as well as transducer problems. Always shut down the unit with the power button, never by unplugging it or disconnecting the power supply from the battery.

Soft Reset
Power unit down, press pages key and power key, hold keys until USA map appears. This will not delete waypoints or other user saved data.

Hard Reset
This method will delete waypoints and trails so be sure to back them up first unless you have no choice.

Shut unit off, press Zoom in, Zoom out, and the power key, hold keys until USA map appears. Unit will reset to factory default, you will need to allow time for unit to reinitialize gps position. This may take up to a few minutes on the first gps position lock.

ok i will give that a try.one more question is when i browsed the mcc files it shows nothing,no data and no files.it seems the new card could be blank,is that possible? it is new in the box with all factory paper work with it.
