Hi all, good to be on this forum and thread. I just tried using the F/A from post one. When launched fron INTERNAL root folder there is a red warning, I guess, saying that "Integrated meta.txt is dated 4/16/2019 02:00 pm". I tried clicking on #1 to update Meta.txt and the return I get is the same red warning. I clicked all the other links 1-4 and 10 which all seemed to work except Patch Navcore was missing the ttsystem file so I copied it from a backup. However I have the fundamental problem of getting the NO Maps Found error which happened after I tried solving the Malformed... error in TTHome. I tried the F/A still having this error and except for the red text got OK's on 2-4. I have done a lot of work on this error: copied all files from INTERNAL to an external disk folder as well as Storage, the SDHC. Then formatted both folders; copied back the files did a reset with the card out; shut the unit down relaunched and still same error. The unit is a GO 730, DEVICE Code AK6S2CAKVE; App version 9510 is reported by F/A; navcore 9.510.1 from the cab file name; map version 805.1801- Current Map=North_America_2GB. The files and map were working recently but I got the Malformed... error in TTHome and tried fixing it unsuccessfully and then was getting the No Maps Found error. Can some kind soul point me to the solution?
