Hey guys, I just bought a 2013 summit white tahoe and have been reading up in these forums (and around the net) to research on some accessory items for it. I have come across this radio alot though...
First off, you guys are looking at the SPH-DA01 which is last years model (The Original AppRadio. That is why it is so cheap. ($150 in the link in the OP)
You guys might want to take a look at the current model which is the SPH-DA100 (The AppRadio 2). Most people actually get these models because of their integration with smartphones.
Those in the know usually follow two options:
A. Use it with their jailbroken iphone for total phone control from the head unit (there is a separate app this requires that would never be allowed on the App Store, hence why it needs to be jailbroken)
or
B. Use it with their MHL or HDMI compatible Android phone, with an app call ARLiberator. This offers full control of a rooted Android phone from the head unit. The phones display is mirrored onto the head unit and can be controlled from the head unit.
I've done quite a bit of research and have ended up at appradioforums.com where you can find more information on how to set it up.
Cheapest i have found the appradio 2 for is $329. The ARLiberator app costs $30, but users don't seem to mind as there is no other *great* solution for mirroring your android smartphone from any vendor.
From the videos i've seen on Youtube it works pretty well. If you use your smartphone in your car and constantly find yourself using it for music or podcasts (or even video for passengers), then this is a good solution.
I've decided to wait to see what the AppRadio 3 offers (hopefully it will be at CES in a couple of weeks) in hopes that it comes with better hookups for audio
the appradio 2 only comes with 2 2-volt preamp outputs if i remember correctly. and the RMS and peak wattage is kinda low.
