ok I updated to the 2.00006 or whatever it's called I did the hask for the speed in the emergancy break before the mod. and I dowloaded the testmode unzipped it and put in on a blank sd card but when I put it in the unit it wont bring up the test mode what am I doing wrong I tried to look for the directions on here but couldn't find them any help would be great

Download the latest version of Testmode

from where ?

The directions may be a bit hard to find since they've been on here for so long but rest assured they are around. If you can't find a link to the latest version of testmode then send me a PM. That probably means it's about time to upload them again and I'll be happy to do it
