Document: i can say its great i installed this in my 2009 zhz corvette and i love it . no problems super v1 mount. and the electical connect is perfect
I have to say, this is a quality radar detector mount. It is made well and installs easily,(with great clear instructions). It looks professionally installed. If you are looking for a quality product to mount your Valentine One, look no further.
Easily installed and fits as advertised. I'll be getting another for the other car. Arrived within 3 days of order. They sent they wrong mount first. A pleasant phone call and the correct one arrived next day with a prepaid return label for the wrong one. = great service!
You will notice that I first installed the mount which took all of a few minutes and then I searched for a power source. once I found the wire, I used the Wiring Harness Connector, Item 20310 which comes with the Valentine One to connect the wire to the Direct Wire Power Adapter which also comes with it. I then connected the plug to the Valentine to make sure it worked (it did!)
When I purchased the blendmount, I received an email from the vendor making certain that the mount would fit my car. I received the mount via priority mail in a couple of days. I asked the vendor a question, and it was quickly answered. It only took about 10 minutes to read the instructions and to install the mount. It looks great, unique, and professionally installed!!!
This is a fantastic mount that just works as it should - it makes the installation simple and clean, the supplier was great and prompt in shipping. I will get another one of these for our second car to allow quick swapping of the V1 from one car to the other.
Must have for anyone with a Valentine. Installation is easy but a bit of pain. You'll have to mount it a little lower so that it doesn't vibrate against the mirror.
Mounting bracket works very well with the Valentine 1. Made of aluminum which makes it very sturdy. Downside is the cost which is a bit high. Great customer service by the seller who contacted me and made sure I had the correct mount for the rearview mirror stem. If price doesn't bother you, it is well worth it.
Excellent customer service. Called me day i ordered the product to find out my vehicle make/model to ensure they sent the right one. Received it within about 4 days of placing the order, and it fits perfectly underneath my truck rearview mirror. It's very functional, much better than a windshield or dash mount.
This mount is perfect easy to install and not sure if everyone knows, in the state of california it is illegal to use the suction mount the Valentine 1 provide you cannot have the radar detector mounted on your wind shield which means you cannot use the suction mounts, click on link below for more information. Anyway you will love this mount on your rear view mirror and they give you all the tools you need to get the job done.[... ].
Answer: This mount, attaches to the short stem between the windshield, and the rear view mirror itself. It in NO way, blocks/restricts the movement/adjustment of the mirror whatsoever. Its a very good item, and I have had no issues with it at all, 2 years later.
