Very easy to install and use. I used it for alpine video bypass for my, uhhh, "boat or RV". Comes preset to use for this function so all you have to do is hook up the wires. The only reason it's not a 5 star is that the video resets every time I restart my vehicle. That could be the head unit though.

I used this to bypass the foot brake and parking brake signals for an Alpine INA-W900BT. Without this device, the only way to access the main setup menu is to set the parking brake, press down the foot brake and while holding the brake pedal down, release the parking brake and set it again, then release the foot brake. Seriously? That's insane. Wire this thingy in and you can access the setup menu any time. Perfect!

First of all, don't buy this unit with the intention of allowing the viewing of DVDs while you are driving. This is illegal and insane (and I'm not just saying that as a legal disclaimer; moving video in the front seat is inevitably going to pull the driver's eyes from the road) so I'm not endorsing that.

That said, I highly recommend this product to make your life easier when installing a new stereo. My Alpine INA-W900BT is a great head unit, but when it comes to hooking up the foot and hand brake wiring, it is a bit of a pain. I am no car stereo guru by any stretch but drilling a hole in my firewall to route a brake detection wire? NO THANK YOU.

Not a whole lot else to say; this item simply does what it is supposed to do. Your head unit will think that the brake is always on, letting you access any functions you need to. In my case, I will be picking up another one for my other car as it is really annoying that my wife can't program the GPS while I am driving. Until the car manufacturers start adding some sort of passenger-detection override, items like this will be sorely necessary.

There's a lot of programming to customize this gizmo for all the various head units it fits. Extensive instructions are included. But it comes ready for the Alpine right out of the box.
And that's a good thing because you can't do a proper set up of the Alpine audio/phone/backup camera/etc unless the video is working (even if you're not going to use the video) and setting up the video requires you to run clockwise around the barn twice under a full moon with a chicken in each hand... naked ..... or just wire this guy in. It's a five-minute job once you get the head unit pulled out.... everything is color-coded, so no worries.

I just picked up a new 2014 FJ Cruiser and the funny thing about the rear window is that the key is needed in the rear door to open the window. You have to insert the key and turn it and hold for 3 seconds. This is just stupid on Toyota's behalf. So I found a nice write-up on how to bypass this functionality using this PAC TR-7 unit and use the key fob unlock button to unlock the rear window. Here is the write-up: [...]

The write-up includes details on the parts needed and steps to take for the install.

The programming on this device is pretty simple, once you get the understanding. You basically hook up the black and red wires as Negative and Positive, respectively, and then use the brown wire by tapping against the ground to program the unit.

In my case, you tap 15 times and you'll see a red light blink for each tap. You then wait a few seconds and you'll see the red light flash 15 times you let you know what feature you're selecting. Next you just tap twice again and it will again blink each time and then blink twice again back letting you know that you selected two. Next you tap once more putting it into a timer mode and the light will blink once back. At this time if you want to program the number of hours, you can tap here, but for my purposes, I don't do anything. It will then blink twice which will be the where you want to tap if you want 10's of minutes in your timing. In my case again, I just let it keep going...and finally it will blink 3 times, for the location where you want to program the number of seconds, and for me it was just 3. Once you are complete with the settings, it will flash the light several times again and you can then hook up the PAC TR-7.

Works great for me so I give 5 stars.

I used it for the Alpine INE-S920HD, everything is literally bypassed. The deck will play anything and let you set anything irrespective of the status of the vehicle. It does the job its supposed to do, flawlessly too. I cannot complain. And the price was good too. Great equipment.

Between the written instructions, online material, and such, this a very capable and well supported device that is straightforward to use.

The various applications map to configuration numbers that you "program" by pulsing the brown lead to ground, while applying 12V power and ground to those leads. This is not a completely obvious process, but with a suitable 12V DC (or slightly more) power supply and a morse key (or similarly-functioning momentary switch) to do the "pulsing", it straightforward enough.

BTW the LED that pulses is on the PCB within the enclosure; if it is on you will know it as it shines brightly from within. This is not documented anywhere I could see but is obvious once your configuration setup is working.

Other downside is that, for my "marine" application #19, (bypass of parking brake for pioneer car audio) a five pin relay was needed (only) to invert the polarity of the output, not for current capacity; this more than doubles the space required and makes the resulting solution a bit awkward, though acceptable when hidden behind console. For applications where relays are not required -- probably the majority -- the unit is small enough to be very convenient.

A direct plug-and-play for Alpine units, no programming needed. Works perfectly out of the box for my Alpine ICS X7HD, I now have bypass for settings and video playback without connection to my brake lines. Would recommend to anyone with an Alpine head unit with navigation/video playback.

I bought this to do the brake bypass (along with a relay) on a Pioneer AppRadio 1 I installed in my company vehicle.

It works 90% of the time...the other 10% I haven't determined whether it is an issue with the AppRadio or the TR7. I'm not deducting a star for that as it doesn't happen enough to be able to troubleshoot it easily.

What I will complain about:

- Programming. Sure, if you just need the default Alpine program it must be easy. But if you need to program it to do a delayed on-off-on, it is a freaking pain in the rear. You have to ground that damn brown wire a ton of times, know the exact sequence to expect for it to signal back, and damn well hope you don't make a mistake or it is programming all over again.

- Could not get it to program off of the vehicle's power. I had quick disconnects on every wire and disconnected everything except power/ground, but for some reason I was only able to do it off a battery on my workbench. I was even using the same ground point the unit was using. Just made life a bit more of a pain.

Luckily, the price is right for this thing otherwise I'd give it 3 stars. They sell a laptop programmable version as well but it is significantly more expensive.

I used this in when installing an Alpine INA-W910 in order to bypass the video/menu lockout. I do not watch video while driving, however my 3-year old is able to clearly see the head unit from the back seat, so that's why I need it.

The unit comes pre programmed to bypass the Alpine, so that made installation really easy. However, when I was testing out the system, it would not work every time so I tried to manually program it; the directions were very straightforward and clear.

My main problem is that the TR-7 is inconsistent in unlocking the Alpine. When I start the car, about 50% of the time, the system is still locked. If I turn the head-unit off and then on again, there is a 90% chance the system will be unlocked. The rest of the time, it stays locked (to my daughter's dismay) unless I wait a few minutes and then try again - once or a few times.

So, it usually works, but if I knew it was going to be like this, I would have just wired a couple mechanical switches to do the job.
