I'm sure this has been covered many times, but the search tool seems to be not yielding any results for me. However, can anyone recommend a good jammer for my two different cars (04 BMW M3 - jet black and 09 MB ML350 - silver). I also have a V1 in both vehicles, if integration/interference is an issue on that front.
I understand that there's one company out there that seems to outperform most in tests. However, after going through the FAQs I was wondering if it's really necessary with the M3. The car itself is black and has a somewhat of an aerodynamic profile, so could cheaper alternatives suffice? As for the ML, I would guess that would need the better protection. Any input is appreciated, TIA.
