How to match midland gxt1000 with cobra am850

Hey. In this spring I bought a pair of midland gxt1000 and last week I have received as a gift a pair of Cobra am850. I don’t have any experience with this kind of radios. Now, in 2 days I’ll go in vacation with my friends so I need to use all radios. How can I match them ? I tried but no succes. Thank you for your help

Sorry I’m late. I couldn’t find the Cobra’s online to assure myself that they were frs/gmrs radios (please check to make sure you got the model right). If they are frs/gmrs,
Set the channels on all of your radios to the same channel. This should work. Also make sure there is no privacy codes set for any of the radios. And since you may not know: channels 1-7 and 15-22 require a license if the radios are able to operate above 2 watts (the Midland GXT1000’s can operate above 2 watts, so you will need one for those channels on those radios; idk about the Cobra’s).
If this info didn’t make sense, please tell me what you didn’t understand. Lol!
