Default 1991 Volvo 240 Nexus 7 Install

A lot of folks have been putting these Nexus 7 tablets in double DIN car stereo bezels. I knew the dash was about the right size to fit it in, but with some considerable alterations. So here's my project so far.

Also viewable via my imgur gallery.

A fitment test. Just seeing where the cables are going to have to go, mostly.

Out comes everything, because I need to do some alterations on the dash framing and repair some things.

Laying on the workbench, you can see that my 23 year old plexi gage cluster has a broken lens. I fabricated up a replacement while I had it out.

This is after I repaired the cluster, recessed the stock radio, which will still be used to drive the audio channels to speakers and amp, and temporarily blocked off the heating vents which will later get re-routed to a vertical position where those two square covers are in the middle of the dash. I added steel flat-stock sections as magnetic attachment points for the touchscreen bezel.

It's close to finished. There are little peg standoffs with strong magnets near the corners, to hold it to the dash frame. Maybe one more basecoat and a protective coating, and I'll mount the Nexus and then I just have some fine points to finish up with the wiring and software. Not pictured is something I picked up from another modder's thread. I didn't want to alter the tablet or damage it in any way, so I put painter's tape around the edges and hot-glued it in place on the back of the bezel. It's pretty firm, and if I ever need to take it out, it's a matter of breaking some of that glue off and sliding it out. the leftover glue will only be stuck to the painter's tape.

I'm about 95% done. Moving the power supply behind the center console and fine tuning settings next. I was using my Galaxy S III in a car mount for music and navigation, and was connecting to the radio via a BluBridge Bluetooth receiver, which is what that second charge cable runs to. I had thought I'd just jack into the 3.5mm headphone port on the Nexus and not have to use the BluBridge anymore, but I ran a test and was getting a pattern of popping sounds in the background. I can only assume it's due to electrical system feedback, but the curious thing is that it doesn't do that when I plug directly into my Galaxy S III. If anyone has any ideas on how to eliminate that issue or troubleshoot it, let me know!
