Live TV in car

hey has anyone that switched to an aftermarket head unit with the TV function tried to watch live TV in their car? I know Canada requires the ATSC tuner/receiver and antenna first since we switched over from analog to digital at the end of August. I have one of those head unit where it gives me the TV option, so just want to see if any members here have tried it and the quality of it. Thanks

Had it on my old Civic and Golf.
Was able to get 2-3 local channels depending where I was. Reception was just as good as any other TV using the old rabbit ear antennas.

i think it is atsc-m/h (the standard for mobile/handheld reception)? also i dont even know if any stations here in canada have upgraded or have the capability to broadcast atsc-m/h.

of course if you are stationary and have a atsc tuner than its just a matter of location and the right antenna.
