No cure for this issue as far as i'm aware. Some people have reverted back to v8.302 navcore to solve the issues. Not sure if thats something you are comfortable with. _________________ Tomtom GO 1005 LIVE
Is there a way to download the previous version again and install? I'd like to revert without having to revert the full backup. Unfortunately, I don't have any of the previous versions saved...
I read in another forum that the map redraw problem might be connected to the use of the RDS-TMC receiver. Can anyone confirm they're getting this without the receiver as well (won't be able to test it myself for a few days)...

JaTe, I have the same issue you describe. Every 20-30 seconds, I lose all map detail for a second. It always re-appears. Have reported it to the people that need to know, but so far, its not a widely reported problem!
Hi Falkirk81
As yet I haven't raised a ticket with TT - will follow up on that tomorrow and see what response I get.
Skywalker - seems that there are a few more coming forward now with the same problem, so maybe TT need to revisit the upgrade.
I've asked TomTom about the map flicker so will see what they say. Meanwhile, found the previous version of NavCore in my computer thanks to Time Machine and I'm now reverting away from this 8.350 crap.

Thinking about it mine only flickered when attached to the RDS-TMC reciever. I have a docking station in the car so RDS-TMC is always connected. It doesn't do it in demo mode in the house. I assumed that this was something to do with demo mode so perhaps they are right in what they are thinking _________________ Tomtom 720T

My boot version is 5.5120 and it is not working.
I also have 5.5120, but don't have any problems with my Go 720. (NB I am NOT using a TMC receiver)

I have a 520 with App 8.50 and Bootloader 5.5120 and up until I got an RDS-TMC recever (type 014 with the round jackplug) I didn't have any problems with a blanking screen.
It now happens whenever the receiver is plugged in, either searching or locked on to a station.
I will be trying the RDS-TMC with my old App 7.20 which is on the Internal Memory. I also have a new SD card on order, so I will put 8.302 on it and try that. _________________ Ric - TomTom 520 DEAD - Passed to the great traffic jam in the sky.

I get screen refres prob every 15 secs or so when icons (and sometimes roads) will disappear. It is only when I have my TMC plugged in.
Other than that the upgrade went smoothly. I do feel the volume is lower although still audible at 90%. It may be subjective or prevailing conditions but I do seem to get a better TMC signal than before.

Also, I don't know if this makes any sense but it seems a full battery is only lasting about 45 minutes now!!! Anyone else noticing a sudden shortening of battery life?
I don't use it on battery, but I was asked by "someone" to do a test on it (thinking TT had "solved" the crackly voice on low battery "issue" by chopping the battery usage! They have a history of solving problems by hiding them in a Navcore update - e.g. stopped switching off with power loss to "solve" the "issue" with dodgy connections on the x10 mounts instead of rebuilding the mounts/connectors). I think these timings were my findings (by memory so might be a bit out). After 40 minutes, the volume became so faint that I couldn't understand anything (that was on a day when my first hour of running was off motorway, relatively quiet so I was able to hear instructions despite the rotten volume "issue" I have with 8.350). After 50 minutes, the sound completely died so no nav instructions, just the map running. After 90 minutes, it died. It was the first and only time I had ever run my TT on battery alone.
To concur with others about the screen blink or whatever, I also run my 920T with the RDS-TMC always connected (the round plug thing with flat egg shaped thingy). When I think about it, I can well believe it could be whenever the RDS-TMC re-acquires an update or signal. I've given up on 8.350 now and rolled back to 8.302, but I do have 8.350 on SDHC card, so I'll try to give it a test with and without. I haven't found the blink too much of a problem, mostly, I suspect, because I don't look at the screen too often until I get into small roads in towns I don't know. It is niggly, though and I can understand people having a real problem with it if it lasts longer than I've noticed. _________________ Dennis

Based on the consensus that says that its likely to be related to having the RDS-TMC connections plugged in, I have both the standard x40 windscreen mount and the new iPod and RDS-TMC enabled mount, so I will give them a go at work tomorrow and see how the flicker fairs! _________________ Tomtom GO 1005 LIVE
