Installing a Beltronics STi-R Plus Radar Detector

Overall I'm happy with it and my install.

This is installed in a 2014 Jeep Grand Cherokee Limited.
Probably took 8 hours total. I did it in phases. I put it on the dash and just hooked up a Cigarette Lighter the first day. Then I did the Receiver another day, controls another day etc.
I redid/moved some things a few times. Probably would take me 3 hours tops if I had to do over again.

I'm giving the STi-R Plus 4 out 5 Stars though. I'd give Max a 3 and a 9500ix a 4.5 (for what they are targeted to be).

I always hesitated installing one of these because of how invasive it was. Especially on a $40K vehicle. This was completely benign. No way I'd let a "Pro" touch my Jeep.
I also didn't like the idea of a $1300.00 unit exposed to the elements. Even though it is very well made to do so.

I was able to install it without a single drilled hole or cut wire.
GPS Antenna is magnetically mounted on the side of steel box above the glove box. I suspect this contains the airbag or the gas for it. GPS Locks before I get to the street.

I tried RDR Off and Segmentation. I started seeing Ka Falses. That was completely unacceptable.
Extremely sensitive to moving K Falses. I now must turn TSR ON to reduce those. So basically it's set completely factory.

Only changes from factory settings is, Speed Display and Highway. I may have to run Auto to get rid of more Moving K falses.

Install:

Packaging and Hardware was absolutely top notch.

I mounted the Interface on a shelf that the owners manual goes in the Glove Box. This shelf just pops out by pulling on it and gives good access.

I only had to fish wires 1.5 feet from center floor console to glove box and from upper corner of windshield headline to door gasket (6 inches).

Excess wire is tucked under center console for display, control, power, LED, speaker, and speaker power.
Excess wire is tucked over glove box for GPS and Receiver.
There is also excess wire in the overhead console, because there is a 3ft lead to a large connector on the receiver. Those 3 feet stayed up top.

I ran receiver wire into the overhead center console out the front of the headliner.
Then I tucked wire along the headliner to the top of the passenger windshield pillar.
Then I had to fish it to the other side of the pillar.
The door gasket just pulls out going down the pillar.
So I just tucked wire in a slot that was behind the gasket.
A panel on side of dash pops out and you can see holes that go into the glove box.

In the center floor console it's open where the door flips up to.
Panel popped off bottom front of center floor console.
There I could reach connecter on cigarette lighter for switched power.
Getting wire from USB port area (in floor console) to that popped out panel was easy.
Then a fished from their up to the glove box.

I used 2 9500ix Visor Clips double sticky tapped to supplied bracket.
The tape is not holding any weight. Just holds clips from swiveling.
I went to the very end of the clip to minimize cater lever effect on the headliner. That is, I want the lift point closer to the center of gravity of the receiver.
It's very secure and very level.
Just catches top of windshield wiper.
Lens will never get dirty or sand blasted.
It is slightly visible in the right lighting conditions.

It has an excellent view of the road and laser has good view too.
Mounting high is less effective for laser detection, but generally good for radar.

When purchasing I really could not get a sense on how big things were. I supplied extra photos to get an idea.
The control panel was much smaller than expected.
Receiver was smaller than expected (good). It's length and height are smaller than 9500ix. It's much wider though.

I think many Radar tests are not real world. They compromise everything for range.
A real test would include Falses and get points taken off for each false hit.
So who knows how this really performs with all the "Range Killer" features enabled.

Pros:

More visibly concealed than 9500ix/Max2 mounted the same spot.
Allows optimal placement for GPS Antenna.
Allows optimal placement for controls.
Allows optimal placement for display.
Allows optimal placement for speaker.
Parts can be modularly replaced.
I can remove any component in 5 minutes.
RDD immune.
GPS locks before I get to the street from home or work. 9500ix would take a couple blocks. Max2 wouldn't lock at all, unless on open windshield.
Better range (no real evidence yet though comparing to 9500ix)
Better off axis. That is quite visible.

Cons: I don't expect any of these ever to get fixed. Even though they all could be.

Software bug that randomly skips voice alert.
Software bug that randomly automutes voice alert.
Software bug that SmartMute should transition all alerts to the appropriate state when crossing the threshold (transition above works, transition going below does not). Exists on 9500ix and Max2 as well.
Beltronics Voice sounds just awful. I may eventually shut it off, but I keep it on because I keep fiddling with settings.
The one button Volume control is awful. The Volume should enable "Volume Mode" then use two buttons to go up or down. Or dedicate another button.

Pictures:

This is trying to show GPS antenna placement. See red arrow. This is looking through the panel that pops off the side of the dashboard at the base of windshield pillar.


My Visor Clips mounted to receiver bracket.


Interface on shelf with Velcro


Close up of controls. Have not finalized LED yet and is taped to speaker.


Driver view of controls.


Driver view of receiver.


Leo's view after being pulled over. Mirror and blackout on windshield blocks view


Front view, sorry for strong reflection. It can be seen with correct lighting.


Passenger view or receiver mounted on headliner


Rear view. See Red Arrow. No lights at night either.


Gives a good idea of how small interface is.


Gives a good idea of size of receiver next to 9500ix

Re: Installing a Beltronics STi-R Plus Radar Detector

As someone who has installed the STi-R plus, I am a bit perplexed. You do know the radar receiver is suppose to be mounted outside the vehicle on the front of the car right?

That is a large part of the integrated-concealed concept of the kit. You can just mount any old radar detector on the top of the windshield and save a ton of money..

The reason I went with the STi-R plus is it's a top unit and I don't have to remove and replace the radar detector every time I leave and enter the vehicle. Plus military bases where I work also require you to remove it, saving me more time. I think someone may see your receiver and think its a regular portable unit and break a window to get at it. Plus those tinted bands on windshields are known to numb the sensitivity of detectors. Just some thoughts! (by the way there is a grommet for the battery cable that you can use through the firewall if you want to relocate the receiver to the front of the vehicle).

They have not seen a regular unit mounted there in 30 years (two cars) I doubt they will now. It's fairly concealed. I've had detectors there and been pulled over several times and the Cop never saw it either. This cost $1300.00 and I expect it to last the life the vehicle, 10 years. I really doubt it would last that long in the grill. It would take a beating exposed to ice, snow, sand, road spray etc.

In the grill the laser lens will get sand blasted over time.

Higher is better for Radar.

I wanted Radar Detector Detector immunity, automatic GPS lockouts, good off axis and I got it. No windshield mount unit does what this does, unfortunately.

I've seen several installations with it mounted in the cabin. In fact, one person made his portable so he could transfer between cars.

To properly install it in the grill often requires cutting the grill which I also didn't want to do. And if you do, it's not invisible either. If you don't it often will be compromised performance. It's working quite well where it is.

Some people install them behind the bumper to protect them, but you lose laser.

It also won't get dirty where I have it and always run at peak performance.

Re: Installing a Beltronics STi-R Plus Radar Detector

I made a mistake in my Cons.

The random missing voice is "SmartMute" engaging (below 20MPH).
The Automuted Voice is still an issue.

I'd give it 4.5 stars but I guess I can't edit old posts.

Re: Installing a Beltronics STi-R Plus Radar Detector

Interesting mounting location. I also thought this model was supposed to be mounted externally.
