Help with deciding between R4W vs R7
So currently drive a 2024 m340i and it’s been a couple weeks since I got it. Really want a good radar and have narrowed it down to r4w vs r7.
Wanted some advice as to is there a major difference between the both ofc the r7 has arrows but does it justify buying the r7 just for that? And if anyone has any good mounting tips that’d be appreciated too.
