Bluetooth trailer brake controllers compared, from CURT Echo in-line and under-dash models to lower-cost 7-way plug-ins, with app and pairing tips.

At a glance

Our top picks

Bluetooth trailer brake controllers move the settings screen to your phone, which changes what you should look at: the app, the pairing steps, and where the hardware physically lives. Three of the five picks here are CURT Echo models that share a design but install in three different places.

We compared the listings by install location first, then by how much each says about its app and profiles. The two lower-priced entries are third-party 51180-style units, and they are placed after the CURT originals because their listings say less about the app experience.

Before you buy

What Matters Before You Choose a Bluetooth Trailer Brake Controller

Key buying criteria so you get the right fit the first time.

  1. 01

    Where the unit installs

    A Bluetooth controller can live under the dash, behind the 7-way socket, or between the plugs. Each choice affects theft risk, weather exposure and how easily you can swap vehicles. Check the title for under-dash, in-line or mobile before ordering.

  2. 02

    App compatibility

    The app is your only display, so your phone must meet its minimum software. The CURT Echo Mobile listing names iOS 14+ and Android 9+, while others do not name versions. Look for supported iOS and Android versions on the listing.

  3. 03

    Pairing method

    Some units pair inside the app instead of through the phone's Bluetooth settings, and doing it the wrong way fails. This is the most common first-install problem. Read the pairing line in the listing bullets before you start.

  4. 04

    Axle and brake range

    Mobile and plug-in models are rated for 1-2 axles and 2-4 brakes, while CURT Echo Under-Dash states 1-4 axles and 2-8 brakes. A triple-axle trailer needs the larger rating. Match the range in the title to your trailer.

  5. 05

    Powered 7-way requirement

    Plug-in models draw power from the 7-way socket's +12V pin. If the socket is dead, the unit cannot run. Confirm the socket is powered or ask the maker.

  6. 06

    Existing controller conflict

    CURT Echo Mobile says an existing factory or aftermarket controller will not function while Echo is installed. That matters if your truck already has a built-in unit. Decide which one you want before buying.

Detailed reviews

The 5 best bluetooth trailer brake controller, explained

01
CURT 51190 Echo Under-Dash Proportional Trailer Brake Controller
  • Bluetooth, triple-axis accelerometer
  • 2-8 brakes, 1-4 axles
  • Stores multiple trailer profiles
Check price on Amazon for CURT 51190 Echo Under-Dash Proportional Trailer Brake Controller (opens in a new tab)
Best for: Larger trailers with app control

Our take

Best for a tandem or triple-axle travel trailer where you want app control and a hardwired install.

Why it made the shortlist

The CURT 51190 Echo Under-Dash is a Bluetooth proportional controller with a triple-axis motion-sensing accelerometer. The listing says it operates 2-8 trailer brakes (1-4 axles), stores multiple trailer profiles, and uses a custom app that monitors brake activity and sends status updates.

Compared with the in-line Echo just below it, it mounts under the dash instead of behind the 7-way socket, which suits a driver who wants the module inside the cab. Against the mobile Echo below it, it covers up to four axles instead of two.

The cost is high, so weigh it against the third-party options at the bottom.

What works

  • Covers up to four axles and eight brakes
  • App monitors brake activity and sends alerts
  • Stores multiple trailer profiles
  • Mounts under the dash, out of the weather

Watch out for

  • Costs far more than third-party plug-ins
  • Needs a vehicle harness and under-dash install
02
CURT 51200 Echo in-Line Proportional Trailer Brake Controller
  • Plugs behind existing 7-way
  • Waterproof sealed enclosure
  • Bluetooth app control
Check price on Amazon for CURT 51200 Echo in-Line Proportional Trailer Brake Controller (opens in a new tab)
Best for: Dedicated tow vehicles

Our take

Best for a dedicated tow vehicle where you want no visible controller at all.

Why it made the shortlist

The CURT 51200 Echo In-Line plugs in behind the existing 7-way socket using USCAR connectors. The listing describes a waterproof enclosure that seals the circuits against the elements, the same Bluetooth app control, and a triple-axis accelerometer.

It is the most expensive pick here. Compared with the Under-Dash Echo, it hides the hardware at the bumper end and trades cab-side access for a cleaner cabin, and unlike the mobile Echo it stays with the vehicle.

What works

  • Hidden behind the socket, nothing in the cab
  • Waterproof enclosure protects the circuits
  • Triple-axis sensor for smooth proportional stops
  • Bluetooth app controls all brake settings

Watch out for

  • Connector style must match your vehicle
03
CURT 51180 Echo Mobile Bluetooth Trailer Brake Controller
  • Plugs between 7-way connectors
  • 1-2 axles, 2-4 brakes
  • OneControl Auto app
Check price on Amazon for CURT 51180 Echo Mobile Bluetooth Trailer Brake Controller (opens in a new tab)
Best for: Multi-vehicle tandem towing

Our take

Best for a tandem trailer owner who tows with more than one vehicle.

Why it made the shortlist

The CURT 51180 Echo Mobile installs between the vehicle and trailer 7-way blade connectors and transfers between vehicles without under-dash wiring. The listing says to use the OneControl Auto app on iOS 14+ or Android 9+ and to pair inside that app, not in the phone's Bluetooth settings.

Compared with the two Echo models above, it supports 1-2 axles and 2-4 brakes rather than up to four axles, and costs less. Its listing notes that an existing factory or aftermarket brake controller will not work while Echo is installed.

What works

  • Moves between vehicles without under-dash wiring
  • Works with cruise control, ABS and PWM systems
  • Zero-tool install on a powered 7-way
  • Adjustable maximum output and sensitivity

Watch out for

  • Limited to 1-2 axles
  • Disables any existing controller while installed

Best Third-Party Features · 4 of 5

51180 Wireless Trailer Brake Controller

51180 Wireless Trailer Brake Controller
  • Five customizable profiles
  • App wiring and connection alerts
  • 1-2 axles, 7-way plug
Check price on Amazon for 51180 Wireless Trailer Brake Controller (opens in a new tab)
Best for: Budget Bluetooth with profiles

Our take

Best for a buyer who wants the plug-in Bluetooth idea at a lower price with real profile storage.

Why it made the shortlist

The SILUXE is a third-party 51180-style unit with Bluetooth app control, five customizable profiles and LED diagnostics for connection, calibration and wiring. The listing describes an app that checks rear-light wiring and warns if the trailer connection is lost.

It matches the TICANEE below on axle range.

What works

  • Five profiles for different trailers or loads
  • App warns when trailer connection is lost
  • LED shows calibration and wiring state
  • Costs much less than CURT Echo models

Watch out for

  • Third-party product, not made by CURT
  • Rated for 1-2 axles only
05
Best for: Small trailers on a budget

Our take

Best for a small single or tandem trailer on a vehicle with a powered 7-way socket and a tight budget.

Why it made the shortlist

The TICANEE is the lowest-priced pick in this list. The listing describes a 3-axis motion sensor, proportional braking, and an app-based setup where you pair inside the dedicated app instead of the standard Bluetooth menu.

It is a third-party unit rated for 1-2 axles and 2-4 brakes.

The listing says certain vehicles need extra steps, so read that note first.

What works

  • No tools or permanent wiring needed
  • Notes cruise control and ABS compatibility
  • Portable between vehicles

Watch out for

  • Rated for 1-2 axles only
  • Some vehicles need extra setup steps
The catch
Compared with the SILUXE above it, it lists fewer diagnostics and no profile count, though it does say it works with cruise control, anti-lock braking and low-voltage systems.

Methodology

How We Built This Shortlist

Each pick was assessed across 5 criteria weighted for real-world use.

01

Install location

We compared where each unit mounts, under the dash, behind the socket, or between plugs, because that drives cost and convenience.

02

App detail

We compared how much each listing says about the app, including pairing steps, alerts, and stored profiles.

03

Axle ratings

We compared the stated axle ranges, 1-2 axles for plug-in units and 1-4 for the CURT Echo Under-Dash.

04

Phone requirements

We noted listed iOS and Android versions and any pairing quirks that could stop a first connection.

05

Brand origin

We separated CURT-made Echo models from third-party 51180-style units so support expectations are clear.

CURT-Made vs Third-Party

CURT-made Echo

Backed by CURT and the OneControl Auto app, with up to four axles on the Under-Dash model. CURT Echo Under-Dash, CURT Echo In-Line and CURT Echo Mobile are in this group.

Third-party 51180-style

Lower price and similar plug-in design, but support comes from the seller. SILUXE 51180 and TICANEE 51180 are in this group.

Choose CURT Echo Mobile if you want the original app and brand, or SILUXE 51180 if price matters more.

By Phone and App Comfort

Want the app plus an under-dash moduleCURT Echo Under-Dash

For Triple-Axle Trailers Specifically

Look for

A stated 1-4 axle or 2-8 brake rating, which among these only CURT Echo Under-Dash publishes in its bullets.

In this comparison

CURT Echo Under-Dash states 2-8 brakes (1-4 axles), while CURT Echo Mobile and the third-party units stop at 1-2 axles.

When to Spend More

Spend more if

Spend more on CURT Echo Under-Dash if your trailer has three axles or you want the app and a fixed install, since the cheaper plug-ins stop at two axles.

Save if

Save with TICANEE 51180 or SILUXE 51180 if you tow a single or tandem trailer and have a powered 7-way socket.

FAQ

Before You Bring One Home

Do Bluetooth brake controllers work with every phone?

Not necessarily. CURT Echo Mobile names iOS 14+ and Android 9+, so check your phone's version against the listing.

What goes wrong most often during first pairing?

Pairing through the phone's Bluetooth menu instead of inside the app. Both CURT Echo Mobile and TICANEE 51180 say to pair inside the app.

Is the CURT Echo worth more than a third-party plug-in?

If you need four axles or want CURT support, yes. For a single or tandem trailer, SILUXE 51180 gives profiles and alerts for much less.

How do I set one up?

Install it, pair it in the app, then set maximum output and sensitivity on a dry, level road. Re-check after loading the trailer differently.

Can I leave it plugged in?

CURT Echo In-Line is sealed for the weather, but plug-in models like CURT Echo Mobile are made to be moved. Store them dry between trips.
