This is probably because sign recognition is programmed for european signs. That is the reason I read from other forums that sign recognition is reading highway signs as speed limit signs. As far as I understand, there is no fix. Thanks for the details though.Been playing around with the TSR. I was so wrong on my assumption regarding the adaption channels Par_country_mode. I tried changing this setting and I was not able to. Tried the security code, changing the session type to VW diagnostic still no go.
I did do another calibration after the TSR coding. I think it improved the recognition but I'm still not able to get it to recognize speed limit signs in Texas. I'm pretty sure they all use the same font across the US. But it does pick up my local high way sign as a speed sign more consistently .
