GMC Universal Home Remote. Frequency?

[Industrial Toys]

No luck at all. Now I tried a Visonic Receiver. Yet another great company, now destroyed by being bought out by Johnston controls. Typical. Long hold times, totally useless call center tech support (with no technical background, or historical product library) utilizing poor quality, low bandwidth IP voice lines. Does anything ever get better or is it all just entropy?

I probably could have gotten better information from my mother, and not spent as much time in doing so. Thanks Johnston Controls!

No luck with what?

With anything really. On the phone with Chamberlain. Try asking a call center rep what frequency a given opener uses?

There was a time when tech support may say, hey, yeah, I designed that thing. Now they just grab any dummy off the street that can read it seems.

Why do you need to know the frequency? :confused3:

To determine some starting point of compatibility. It's mind boggling. Lear, who made the GM console touts it as being able to control a myriad of devices, openers, gates, security, but can't for the life of them, give any idea as to what other devices their product has been known to work with specifically.

It's like so many things. The consumer is left to fend to his own devices. And Forums will always put Big Corporations to shame as far as providing any good information.

It's called the homelink. It works with most modern stuff. We use it on my in-laws 2008 Toyota Sienna at their house and our house, buttons 1 and 2 respectively. I use it at our house and their house with the same buttons in our Impala.

I don't think the Lear unit in my 08 is of that generation to support HomeLink. That being said. Three buttons doesn't give a whole lot of options.

ok. is that the lear car 2 U thing in the Sierra?

This should work. It's the same thing as the homelink unit I was showing you, but made for the Car2U.

This is likely what I need. Neither my 2011 GMC truck nor my wife's 2012 Chev Tahoe work with garage opener, Chamberlain told me I needed the Homelink repeater to convert to Security +2.0, but I bet now after reading the description that I need the Car2U repeater instead, not the Homelink repeater..

Description from link above..

One repeater can control multiple cars and openers; if all vehicles in the garage are HomeLinkｮ, only one HomeLinkｮ repeater is needed. If all vehicles are Car2U, only one Car2U repeater is needed. Both repeaters are required if different vehicles sharing the same garage have systems made by both interior suppliers. Consult your vehicle owners' manual if you are unsure of the system installed in your vehicle. HomeLinkｮ Repeater Kit HomeLinkｮ is available in many brands of vehicles, and is identified by a single red LED and 3 buttons; some models may have a "house" image on the panel. On mirror applications, the house may be absent but there is still just one LED. Most older vehicles and select newer models will need a repeater to upgrade the vehicle to be compatible with the new Security+ 2.0 radio code. Gentex Corporation has a website to determine vehicle compatibility; go to HomeLink and follow the steps to program a vehicle to see if you need the kit. Sample HomeLink in-vehicle system Sample HomeLink in-vehicle system Programming HomeLink-equipped Vehicles to Older LiftMasterｮ Garage Door Openers & Gate Operators To program older LiftMaster garage door openers (manufactured prior to 2011) to your HomeLink-equipped vehicle, visit HomeLink and follow the instructions. Car2U Vehicles Select 2007?013 GM & Ford vehicles may have Car2U remote systems manufactured by Lear Corporation, identified by three yellow LED lights, one above each button. The HomeLinkｮ repeater will not work with this system. A Car2U repeater purchased from Lear is required for all vehicles. Contact Lear at www.learcar2u.com or at (866) 572-2728.

Edit: yep, checked my vehicles, both have the 3 led/3 button setup, so I need the Car2U instead of the Homelink..
