@hmmm - avcr not a good idea under the steering wheel. Kind of defeats teh purpose really.
I think they are great for monitoring the car - knock sensor, boost levels, accrurate speed etc... and so in eye sight is best.
Mine is similar to the pic posted with both beside each other. Nothing showing on dash for the stealth look to keep prying eyes out !
Alternatively, there are those that build into the dash - removing cigarette tray etc etc and even heaters!
Go for up on window! It makes most sense and is real handy!!!!
Also, often when driving on low boost a motor comes up behind.. 2/3 presses ( unless u have a scramble button) and you are into high boost and gone... If this was mounted on dash or under steering wheel makes more harder etc etc...
Your call but I would recommend up top.
