Everyone says how to do the patch and activation procedures, and blah blah. So far I have made dozens of models including nav 2 and nav 4 even I have only stayed with nav 2 and nav 4 for everyday use because with nav 3 I am facing a problem that I cannot solve. No one is talking, or at least I haven't found what needs to be done to properly operate a nav3. Both with the normal patch and the truck patch, the gps works for a few hours, then it gets harder and harder, having to restart it to get it working again. Is there any secret to them? Do certain files need to be deleted? Please answer only those who patched them and then tested them on the road for a few days. And I had via and start models with 2gb and 4gb and 8gb. Absolutely they all have the same behavior. After it works for a few hours, when you want to give it an order, it responds very, very hard. Text written with google translate, I'm sorry if some expressions are not understood. Thanks!

Sometimes using TTActivator on NAV 3 Devices it seems to not uninstall and reinstall things correctly
When this happens to me and there are errors I do this and it always comes good again. (Even if I've done some things before I do it all again in this order)

1. Tools Tab > Update Meta
2. Map Downloader Tab > Choose the Map you Require, UNTICK "Auto Extract" then "Download to Folder" to save it as a ttpkg file to your hard drive. Make sure the tools says "Good News a Meta is available for this map"
3. NAV3/4 Tools Tab > Delete Speed Cameras > Reboot Device
4. NAV3/4 Tools Tab > Delete Map Files from Internal Memory > Reboot Device
5. NAV3/4 Tools Tab > Uninstall Patch > Reboot Device
6. NAV3/4 Tools Tab > Install Patch (Choose Either one) > Reboot Device
7. NAV3/4 Tools Tab > Upload Meta to Device > Reboot Device
8. NAV3/4 Tools Tab > Install TT Package Files > Choose your Map File that you downloaded in Step 2 > Reboot Device
9. NAV3/4 Tools Tab > Install TT Package Files > Choose any Speed Camera TTPG Files you want to add > Reboot Device

I always upload the Speedcam files separately to the Map File as I have had a couple of times where I tried to Add the Map and Speedcams at the same time and the speedcams didn't detect after the reboot.

I did all the steps you said exactly except the one with the maps. I wanted the Truck map and had to put it on the card with R-Link Explorer. It didn't work with Tools from TTactivator because of the small space of the GPS. (3.5gb free and the map was 4.7gb) I will see tomorrow when I go by car if it still becomes slow after some time.

The problem is the microSD Card..not the patch
If you install inside internal memory, no freeze

you need faster microSD card by good brand...Kingston Sandisk...may be you need to partition it, max 16Gb for R-link explorer
