Stumbled onto this the other day with my stock AC delco radio in my 91 Camaro.

Set radio to station, press set button, then press two station buttons at the same time. I only bothered to set three extra stations in this manner using combinations of 1-2, 2-3, and 3-4. My finger spans between the buttons nicely so it is easy to use these combinations even when driving. There is no reason why you could not carry this out further with other combinations but it might not be safe to try using combinations such as 1-3 or 1-4 while driving.

Give it a try - it worked for me.

Both of our thirdgens, as well as our 99 Silverado 3500, had that feature. Only works with buttons that are next to each other (ie no 1-3 or 1-4 combo).

 

i could be wrong but i think they are programed to accepted the 1-2, 2-3, 3-4 combinations and not other "dual button" combinations. i would try it but i took my stock radio out a couple of years ago. try it if you want but i dont think it would work.

I will take the extra 3 presets. Living with 4 made for difficult choices.
