In reference to my post about odd lines appearing on the Twonav 7 track from "Why`s it doing THAT ?" from >>

Could you give me assistance in getting a screen-shot and/or a file into a post so I can get some answers to my problem .

Technical help afterwards to rectify the wayward track lines may be required .

Hi. This probably won't help but may explain somewhat. I heard a news story recently about possible interference to the very weak GPS signal, from

increasing Solar flare activity
microwaves
SBS TV signal (Artarmin (? sounds like))
computers and other electronics
(the new 4G signal, in the USA)
can depend on the individual receiver
A GPSr in the UK thought it was in Norway

It apparently may show up on a GPS receiver as erratic tracklogging but I can't say that I've noticed any disruption here.

We had the 2 units running side by side and one was effected , the other wasn`t .

I`m guessing the 'weak signal' filter may have something to do with it , but I need to find out how to fix it or stop it from happening again .

As suggested by Nicko in the original post , I`ll take a photo of the screen(s) to show the bizarre lines . It turns out after zooming right in , the lines aren`t coming from waypoints , but part way along the tracks .

I don't know about TwoNav 7 as I have an Aventura.
When I connect it to the PC (Win7) two folders open:
One called TwoNav, & the other called TwoNav Data.

The track logs are in TwoNav data.
Can you do this & copy & paste the tracklogs to a new folder on your PC?
