Multiple Element Arrangements [Abstract]
Multiple Element Arrangements	(5) MULTIPLE ELEMENT ARRANGEMENTS The Company bundles the sale of its PPL trucker navigation and other selected PPL navigation products with ongoing access to its AURA speed camera database in order to allow those customers who so chose to update their databases for both navigation low bridge height data (perceived as critical to some professional drivers) and speed camera locations. However, in order to receive these updates to these fully functional products, customers must first register on PPL's website. The Company deferred the revenue associated with the ongoing service period, which was considered a separate unit of accounting. Revenues deferred from this arrangement were calculated using the relative selling price method based on Vendor Specific Objective Evidence ("VSOE") and amounted to $935,000 at March 31, 2012 and $928,000 at December 31, 2011. In addition, the Company's domestic business sells products bundled with access to the AURA database. Revenues deferred from these arrangements were calculated using the relative fair market value method and amounted to $165,000 at March 31, 2012 and $214,000 at December 31, 2011.
