Is there a ROM that will allow me to just see a split screen of google maps and waze?

Please, can anybody help me?
I´m Timur USB ROM on my Nexus 7 2012.
It´s all ok. I use a OTG Y cable, the tablet charge, but the tablet don´t recognyze the USB (pendrive, sdcard...)
It´s a general problem of the Timur Rom?

Please, can anybody help me?

I bought some cables and got only one working. Not sure why. In the end i ended up creating my own cable.
Are you powering the tablet from usb charger or computer? try a usb charger.

the cable schematic should be like this

Instead of adding a 100k ohm resistor. a shunt between GND and SENSE should also work.

I bought some of these:

Found N7 2012 with cracked screen while cleaning home and already ordered new LCD with frame. I'll be putting this on car for navigation, music and bluetooth connection to my phone only. Only thing I'm not sure is should I go with USB DAC + amplifier or something like Fiio 10? For now, not looking to replace headunit but a simple mount.

I'm planning to do the same, with a Nexus 7.

Can anyone tell me if there are any issues removing it from the car and using it at home like a normal tablet, if using the Timur ROM?

Thanks!

NOTE: RE: "not looking to replace headunit but a simple mount."

You can check the RAM Mounts brand Tab-Tite spring loaded mount/cradle. I used one for my Xperia Z Ultra and the Z3 Compact tablet too.

This one includes cups to hold the Nexus 7: Part# RAM-HOL-TAB18-CUPSU
Note that there's also a -TAB16- for using the Nexus 7 with a thinner case, I believe.

I just recently finish installing the N7 as a secondary media consumption device (THIS IS NOT A FIX INSTALL, I'M ABLE TO TAKE THE TABLET OUT EASILY), along side my car's original radio. Here's my experience:

By today's standards, our beloved N7 is old and slow, keep that in mind!

I tried many roms and configurations, following the ideas and experiences described on this thread. I settled on Omnirom homemade 6.0.1 (Page 7 or 8 on this thread) which is a fast rom and comes with DC kernel which allows for double tap to wake and OTG + CHARGE, after a fastboot boot flash.

Also, Parrotmod memory fix is a good idea.

The cable for OTG is the second one on the OP, great quality and works as advertised.
PEM is good for killing coms and sleep, once power is not detected, thou is a little bit slow, you can rely on microdroid to manage the screen.
Overclocking to 1500 MHZ max and 340 MHZ min is stable and provides great results. Also, kill windows animations and keep activities to 4 max.

Xposed framework is a good. I use it to control rotations, so the tablet always chooses landscape.

I use Car Luncher as interface, with spotify and youtube as main sources for media.
GMAPS works horrible, our tablet is way to slow. I use gmaps go, which is usable. If anybody has any ideas for this, is highly appreciated.

The DAC is a must, sound is so much better once you take the audio processing out of the tablet. A cheap ground loop isolator is a good idea if you don't wanna have noises

I also flash dolby atmos app from the themes and apps thread, works good.

overall, if you are not going to use the tablet for anything else but media consumption and maybe maps, this tablet is still a good idea.

Now, I'm trying to sort a problem which has been address here but not resolved. Whenever the tablet looses power on OTG+CHARGE, you have to unplug and replug the cable in order to have it working again.

Also, I bought a cheap bluetooth remote control, I'm still trying to get it perfectly.

I'd problems on both Timur and AutoDroid. On both, no sound from DAC (Soundblaster E5) tho can control volume and both had few reboots when OTG cable is unplugged. Android AOSP 7.XX by AnDiSa works very well on grouper but was getting too much static noise on sound through DAC. I'll try OmniROM now.

Not tested for long but don't think I'd problem of losing power.

Get a ground loop isolator for static noise.

Get a ground loop isolator for static noise.

Tests were done at home using headphones out. Sound is fine with DC kernel from July 2017 which someone here modified but only works at boot. Anyway I tried omni and couldn't even charge phone so I'm back to AndiSa's excellent 7.x AOSP rom. Charge, USB drive read works out of box and the rom is very fluid. Headunit remix for android Auto works very well. My DAC SB E5 has bluetooth so can use that option instead. Now need to figure out sleep/wake with some automation and would be grateful if someone can post their settings. I prefer simplicity of PowerEventManager but can't find anything on search on how to setup.

Edit: On all ROM, I'm having issues with waze with black background and no map.

What do any of you plan on moving onto when your Nexus eventually dies? I have had mine in the car for 5+ years now and it is starting to slow down, understandable, it's been rock solid and I am sure was not designed for the environment it was kept in!! But, trying to find a replacement is proving difficult, Timur's kernel made running the Nexus a piece of cake.

I have a Galaxy Note 10.1 2014 that I looked into trying to use, but I don't believe USB Host Mode works on it. I know it is also a few years old, but is barely used, runs a much newer version of Android that my Nexus and the display would be awesome in the car. But, that USB host mode is a deal breaker. I can use Tasker / Secure Settings etc to put it to sleep, but not being able to use a USB hub, Joycon etc. puts a stop to even trying to modify my dash to fit it.

Any suggestions on newer tablets? Or should I start stocking up on good condition used 2013 Nexus 7's?! Which at this point are also knocking on 5 years old already.

Reboot

Hi!!
How can I reboot with the timur kernel 2012? Can it be possible?

Thanks in advance!!

Nexus 7 (2012) grouper with Nougat 7.1.1 for car system

Hi folks!
I’m working on installing my 2012 Nexus 7 grouper with Nougat 7.1.1 into my Ford F-150 truck. My Nexus is rooted.
I’m concern about the USB issues. I’m confuse about the kernel for this issue. If I install the Timur kernel would it conflict the Nougat 7.1.1?
I am new with all this. What do I need to make all of this to work?

Waze on Nexus 7

Is there a ROM that will allow me to just see a split screen of google maps and waze?

You can on 6.0 and above (I think 6.0 requires allowing that somewhere in system, 7.1.2 is fine) but one of the windows of split screen won't be refreshing until you touch it. It's either Waze or Gmaps. Other option is to run Waze full screen and then let Gmaps show notifications and/or voice guidance.
Also see below..

Tests were done at home using headphones out. Sound is fine with DC kernel from July 2017 which someone here modified but only works at boot. Anyway I tried omni and couldn't even charge phone so I'm back to AndiSa's excellent 7.x AOSP rom. Charge, USB drive read works out of box and the rom is very fluid.

I prefer simplicity of PowerEventManager but can't find anything on search on how to setup.

Edit: On all ROM, I'm having issues with waze with black background and no map.

Waze is behaving odd on custom rooms higher than 5.1.1.
What I found so far the problem lies in Waze graphics engine as of version 4 and above.
Solution is to use original Android or Waze version below 4.0.
This worked for me. Get it on apkmirror.com
If anyone finds a workaround and manages to run newest version of Waze please post it here along with the set up or way hoe to do it. Will be greatly appreciated.

My e46 is sporting one Nexus 7 2013 wifi only. I'm using this ROM https://xdaforums.com/nexus-7-2013/development/rom-usb-host-based-rr-timur-s-t3659332 with the following setup
MicroG -NanoDroid Magisk module + fake store installed through Xposed Framework.
Greenify, Naptime and Amplify for app hibernation, doze and alarms/wakelock coalescence
Macrodroid for automation (not a Tasker fan and MD does pretty much everything you need)

With this setup Waze fails to aquire GPS lock Maps does aquire the gps lock but after about 10 minutes which is an inconvenience. My workaround was to use Offline navigation from F-Droid repos and it works flawlessly.

I have to mention that even though the ROM posted above has been abandoned by it's developer and has minor bugs, there's little to nothing that can't be fixed.

The tablet is quite loaded as i run nova launcher, zooper widget, torque, poweramp, spotify and many other heavy-on-usage apps and even so i have a loss of 2-3% battery over 24 hours, and that has to do with "network location services" trying to find GSM network (?)
