We told you this is just going to snowball. After showing you a Nissan cube with a Google Nexus 7 tablet replacing its head unit, here we have a Chevrolet Cruze with an auxiliary Samsung Galaxy S2-based infotainment system to supplement the car’s factory head unit.
Over at the CruzeTalk.com forums, user wmschoonover said he initially thought about running a “car-PC type replacement system” and doing away with the factory head unit in his 2012 Cruze LS. He later thought better of that, deciding to keep most of his factory stereo’s functionality while adding on the Samsung Galaxy S2 as an extra kick in the pants. Here are his details from the original forum thread, slightly cleaned up for clarity:
[I] still have full functional use of my stereo/XM/setting controls/etc., but when I switch to AUX, the fun begins. I have it set to power up when the car is turned on or to AUX power (currently through a usb cig adapter but will be hardwired soon) and by using Anyscreentime (app) it prevents the unit from sleeping, although it dims when not in use, and when I turn off the power it sleeps within a minute. Currently [I] have to pause the music before it sleeps, or it will run while the car is off, but [I'm] looking into app killers to pause or stop the music app when it sleeps. I have full GPS routing which mutes the music to tell me when/where to turn. With a Bluetooth OSB adapter, you can use an app to monitor your tach/speed/etc as well as check your codes. Still getting a few more tweaks, but I’m happy with the outcome so far.
The original poster did eventually hard-wire his rig so he wasn’t having to use the cigarette lighter plug. Meanwhile, an Australian forum member named thorpee, whose Holden Cruze appears to be basically the same as the OP’s except for the location of the steering wheel, used the same method and took what he called “heaps” of photos. Charmingly Australian wording, and a very clean install when all was said and done. Hit this link for his full photo gallery at imgur.
