I have a 3.5mm aux jack in my car that I currently use for an MP3 player. I'd also like to be able to use the jack for a Sirius XM unit. To avoid having to plug and unplug each device as I use the other, I thought I'd grab a cheap splitter or switch in order to keep them both plugged in full time. Because of price, I was hoping one of these or these would work, but was told those are really for splitting a single outgoing signal into two (like one MP3 signal into 2 sets of headphones). I was told plugging two devices into one outgoing signal could damage my system. If I only intend to use one device at a time, is there any problem with one of these products?
Or is something like this what I really need? Anything cheaper than $30 out there? If not, I might just manually switch plugs as needed.
I wouldn't use a splitter unless it had a switch. Are you sure your radio does not have a Sattelite radio connection port in back? If so you just plug a tuner in there and it stays hidden inside the dash but that kind of Sat receiver is different than others. It is made to be controlled by the radio.
The factory radio is sat ready but I need to buy a tuner from Mazda for several hundred dollars to make it operational. The aux jack is my best bet and it sounds like an A/B switch is preferred over a splitter. I think if I have to go through the trouble of flipping the switch when I want to change devices, I might as well just quickly swap the plugs.
