Hello there! does anyone know where I could get a decent idiot guide on how to operate the above tacho unit?
I have always used the Siemens version and found it relatively easy to use, however on Sunday I got a Stoneridge for the first time and found it a nightmare.
It was a big achievement to get my card in and out and as for manual entries… 
Other drivers helped me out, but I’d like to read up on them and have a guide as back up til I’m used to it.
Thanks in advance if you can help.
You can download a simulator for it HERE so you can play away to your hearts content and not ■■■■ up your card or shift.
