Overview
A windshield suction-cup cradle built specifically for Uniden's R-series and DFR-series radar detectors, not a universal mount. A metal slide-in cradle with an adjustment screw knob holds the unit steady, and the reusable suction base can be rinsed under warm water to restore grip once it weakens.
This is listed under a Radar Detectors category, but it is only the windshield mount, sold separately from any detector. The seller's own compatibility list names the R1, R2, R3, R4, R6, R7 and R8, the LRD300 through LRD950 line, and the DF1 plus DFR2 through DFR9, then separately marks the R7 as not compatible. That is a direct contradiction in the listing itself, so an R7 owner should confirm fitment before ordering rather than trust either line alone.
- Metal slide-in cradle with adjustment screw knob
- Reusable suction cup, rinse under warm water to restore grip
- Built for Uniden R1 through R8 and DF1/DFR2 through DFR9
- Sold new in sealed packaging with a manufacturer direct-replacement warranty
Who it's for
Uniden owners who need a replacement or spare windshield mount for a listed dash or cordless detector. Not for anyone whose detector brand falls outside the Uniden lineup named in the listing, and R7 owners should treat fitment as unresolved rather than confirmed.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reusable suction cup restores grip with a rinse, no replacement needed
- Metal cradle with screw-lock adjustment resists road vibration
- Covers a wide span of Uniden R and DFR models
- Listing contradicts itself on R7 compatibility
- Generic brand field with no stated warranty length beyond a direct-replacement promise
- Mount only, no detector or charging cable included
Performance notes
The suction base holds through normal driving vibration once seated on clean glass, and the listing notes that rinsing the cup under warm water and letting it air dry restores grip if it starts slipping. The metal cradle plus screw knob is meant to stop the detector from rattling loose over rough roads, unlike a plain plastic clip mount.

Questions about the Car RX3+UN01
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Does this fit the Uniden R7?
The listing is contradictory: one part of it lists the R7 as compatible while another explicitly marks it as not compatible. Confirm with the seller before ordering if you own an R7.
Does this come with a Uniden radar detector?
No, this is only the windshield suction mount and cradle. The detector itself is sold separately.
What do I do if the suction cup stops holding to the windshield?
Rinse the base under warm water and let it air dry, which the listing says restores its grip.
