I recently fitted a 120° dash-cam to the inside of my GLA, it's a Next Base 402G Professional, it's a higher spec model that also offers static recording when you're away from your car via infa-red sensor, G-sensor/GPS for speed, role and positioning should the worst ever happen, plus the usual cam things...
The GLA has a perfect fitting spot just behind the interior mirror, most cameras can fit here (I tried a few out first before buying mine to be sure it fitted okay). The power cable slips up to the passenger sunvisor and clips behind it neatly (with some 1€ clips). Then the cable runs along to the door frame rubber, where it fits underneath and then runs all the way down to the inner foot panel. After that you push it behind the lower panels so it's out of sight before it resurfaces at the ashtray lighter to be plugged in. You can wire it into your system, but I like to keep my system mobile.
The view is pretty good, the GLA bonnet is barely visible plus the window pillars give a nice clear wide view for the camera. If you are thinking about a dash-cam then you shouldn't have any problems with fitting one to the GLA as it's windscreen is perfect for a basic systems up to the more expensive wide lense models... you can see the screen grab from the film how wide it is (there's actually more on the right side but my screen cut it off)...
