Yes, FreeFlight and Jeppesen have developed a "4MB Upgrade Program" for the Approach & Approach Plus systems.

The upgrade will entail a minor hardware modification, software upgrade, and a higher capacity 4MB data card. With this upgrade, pilots will have continued access to the Jeppesen NavData©.

Approach and Approach Plus model upgrades must be completed by June 4, 2009 to be able to continue to receive Jeppesen NavData© services.

This upgrade is applicable to all FreeFlight Systems TSO-approved Approach and Approach Plus GPS Navigation Management Systems (including I/O models) and equivalent legacy equipment with the Trimble name. Including: TNL 2000 Approach & Approach Plus; FreeFlight / Trimble 2101 & 2101 I/O Approach & Approach Plus.
Newer FreeFlight 2101 I/O Approach Plus models ending in -32, -33 or -42, with MOD 14 marked out, have already received the hardware modification and may be updated in the field.

The "4MB Upgrade Program" enables customers to contact their dealer directly to arrange for your systems to be returned to the factory for the necessary hardware, software upgrades & new data card. Factory pricing will vary depending on upgrade requirements. Contact Southeast Aerospace for more information on your upgrade options.

To provide further information, FreeFlight has released Service information letters, SIL FFS02 & FFS03, as well as FAQs.
