Hi guys , I've owned a V1 for 4-5 years but I just changed car and I want something "superior" for my new car. I want a custom installed RD instead of windshield RD for this car. GPS is not necessary but sounds cool ( will any of the GPS RD have FR database ? ) As far as I understood we have low K band only I already have LJ I read somewhere we need to mount RD vertically in EU ?? Is that correct ? Any difference between fixed radars vs mobile radars ? Thanks guys for your answers.
