Wow...so I just got my R3 yesterday, as it seemed to be the best reviewed system, also managed to drunk order a V1 on amazon but it has not shown up yet, but it looks like it will need a lot of tweaking and add ons (but I have wanted that since high school, when 400 bucks was a ton of money). So far I am not impressed with the r3. Drove 16 miles each way today and it beeped probably 12 of the 16. only times it seemed it did not beep was passing a cvs etc - guess the gps filtering is working. Something on 24.123/4 and 24.199-201 was constantly pinging. I have a 2017 Mercedes e class - I think my car used 77ghz for all of its automatic gizmos but it’s practically worthless in its current configuration. Saw a post a few down on settings so will reprogram and try it again - I’m in the Florida Keys and it’s a holiday weekend so it’s down to stop and go traffic so not heading out again today if I can avoid it.
