Uniden R4 vs Uniden R7

“I just did the reverse. I gotten rid (returned refunded) of my 20 - day old R4 and switched over to V1G2. My R4 GPS fried after firmware update and I tried every trick in the pony playbook but nothing worked. It took CS 2 weeks to reply my first email, with an answer lifted of the IT Squad meme. V1G2 has no GPS, so no such issue. Opened the box and installed it, coonected it to their APP using BT, the update just popped over without any intervention. Has been hooking it up to JBV as its control unit from my android and works like a charm for me so far. JBV does the muting based on GPS POIs, etc. And, the suction cups of my R4 fell off after 1 day use. The V1G2 has been stuck for 1 month. Same setup trick, use saliva. YMMV”

“I called Uniden. They told me the R7 is not an “extreme long range” detector and doesn’t offer the same long distance detection as the R4. Amazon is mis-advertising and the chart is correct. There you have it! For me I care more about detection and sensitivity than the little arrows. And with certain police radar, driving 80 mph, even one second makes a huge difference.”
