Thank you for TT Act 1.20. Lately it is not displaying or picking up my nav3 device, and when it does connect it is not seeing/listing all components, even after using TTom Mydrive Connect to update old firmware. That would mean cable is ok, and I have discovered low or weak battery often causes connect issues. The firmware version is supported - #3 on that list. But does appear to install ttpkg files. Looks like something changed, and I will try another machine to isolate suspicions. Unrelated to that my old XXL IQ routes ones, some developed an unresponsive DONE button, where there is also a light touchscreen bruise in lower LH corner. I believe this is the battery has swelled up, and throwing out touchscreen co-ordinates. TT may get their wish - as 16 years is a pretty good innings relative to defective Navman S80 batteries from the day it was made. I managed to pick up a recent start model for $40 secondhand with lifetime maps - and did a map update to 1125. No action required at this stage, as I try high current charge dongles next.
