Navigation database cycles include both the new and old formats. Make sure to select the Navigation databases for GTN Main Software Version 6.21 or later when downloading databases from fly.garmin.com. -NOTE- For installations with GDL 88, GTN Main Software Version 6.62 is compatible with GDL 88 Software Version 2.05 and later. Please contact Garmin for any additional details. TB 429-20-64 Page 6 of 61 Approved for public release. PART 1: Record the current GTN 750 configuration settings. (Step 1 through 44) 1. Prepare the helicopter for maintenance. 2. Press and hold the GTN 750 “HOME” key. Apply electrical power (28 VDC) to the aircraft using an aircraft grade Ground Power Unit (GPU). Release the “HOME” key once the screen brightly displays “GARMIN”. -NOTE- If the aircraft has optional (429-706-XXX) and/or custom equipment installed (429-799-XXX and/or 429-899-XXX) and/or 3rd party supplemental type certificated (STC) equipment; it is possible some GTN configuration settings may be different from the settings defined in the following tables. If it is the case, and as instructed in Step 3; note the “as displayed” setting nomenclature in the “PART 1” column. Let it be noted that any change to the defined GTN unit parameter settings should be justified either by approved data or by an applicable “flight crew parameter” option” from the “Home/System” page. Consult the applicable optional equipment Installation Instruction (II), Maintenance Manual (MM), or custom equipment drawings and/or Instruction for Continued Airworthiness (ICA) for these specific configuration setting approvals. 3. Using the following tables, record the current GTN 750 configuration settings in the “PART 1” column by making a check mark (√) and by circling (or writing) the current setting nomenclature. Additionally, record the aircraft serial number at the bottom of each page of this Technical Bulletin. TB 429-20-64 Page 7 of 61 Approved for public release. 4. From the Configuration Mode page.
