In my old Toyota FJ Cruiser I used a Nexus 7 tablet running AUX into a single DIN radio that was hidden behind it. The setup worked well but it was a little busy.

For my new (old) 1999 Jeep Cherokee Sport, I thought I'd have to get a different tablet because of the 1.5 DIN size. I didn't want to cut into my entire dash and mold a cradle for a DDIN (I'm much better at computer stuff than that). Holding the Nexus 7 up to the dash, the bottom Navigation bar and top status bar were cut off. So, I bought a smaller tablet (Xperia Z Ultra) but it wasn't anywhere near as capable for an audio setup as the Nexus 7 tablets are; I ended up returning it. I then had an epiphany, why not just decrease the portion of the screen that's usable on the Nexus 7 so it fits a 1.5 DIN opening.

Download a terminal emulator app for the tablet and make sure you have root. Apply these codes via the app to decrease the vertical dimensions of the N7's screen to fit 1.5 DIN:

su

wm size 980x1920

wm density 260

This makes the tablet go from this to this .

After you enter the wm size, you will probably lose the nav and status bars. Don't worry, it's because of the density. Just type in the wm density code after that to get them back. If you're going for different dimensions, mess with the density by entering a low number and then increasing it by 5 until you find the sweet spot. At some point you'll lose the nav/status bars so you know to back down to the density right before that one.

To get back the original screen dimensions/density, input:

wm size reset

wm density reset

The screen dimensions and density changes do remain even after rebooting, so you only have to enter it once.

From here, these are the products I used for my setup:

$29.95 - Nitro Bmw-x43 300 Watt 4 Channel Car Amplifier (don't need a bumping sound system so this is plenty for me)

$38.61 - Fusion MS-BT100 Bluetooth Dongle for Fusion Marine Stereo Head Units

$2.69 x 2 - DB Link Double Shielded Competition Series CLY2MZ 2 Male To 1 Female RCA Y Adapter

$5.96 - Car Charger Power Cigarette Lighter Female Socket Black w 26cm Cable

$9.99 - PowerGen 4.2Amps / 20W Dual USB Car charger Designed for Apple and Android Devices

$7.99 - Super Strong Neodymium Disc Craft Magnets 1/4 X 1/16 Inch N42 (Set of 100)

Tap the amp, bluetooth adapter, and cigarette lighter socket into the ignition, so it receives power when the ignition is on and doesn't when it's off. From there, plug the USB charger into the socket. One USB cable will power the tablet and the other will power the wireless charger.

Take the neodymium magnets , tear down a wireless charger, and add them to the coil .

Make a vinyl template for the size of the ashtray and plastidip it black (it sits flush now, in this image I layed it over the top of the ashtray). I taped the wireless charger to the underside of the vinyl template using super strong Gorilla Glue duct tape.

From here, make a 1/4" piece of wood that's wide enough to screw into the slots the factory radio screwed into . I taped one side down because the tablet was sitting over that screw.

Double side sticky tape the tablet (either directly or using a case) onto the wood . You'll probably need to do it a few times to get the dash to line up correctly.

Remove the center console, pop out the ash tray, and run the USB cable to the wireless charger+vinyl. I then used some super glue to glue it into the slot.
