Kuchar,

absolutely awesome install. I have a Saab 97x which is a trailblazer like yours. I wanted to ask you on the hubs. I have my N7 connected with an OTG Y-splitter going to a powered hub (thru the cigarette socket, hardwired). I simply cannot get the rearview camera or USB drive to connect to the phone.

If I plug the USB drive directly to the female end of the y-splitter, the N7 reads it. I am using StickMount and also Timur's latest ROM (for the N7 2013).

How did you connect your rig to the hubs? I tried following your diagram, but my setup is simpler and dont have/need two hubs.

Thanks for the help and great job.

Did you try restarting the tablet with everything hooked up to it? You might need to do that. That's what I had to do to get mine working...

Yes sir, I did, several times. Still cant get anything to be recognized.

Maybe someone can help with my issue.
I run also USBROM on my N7 3G, the Y-USBOTG cable is connected to an unpowered hub. To the hub i have connected a Sabre USB-DAC and a flash drive.

The flash drive is always shown as a slave device under the usb host settings, but after waking up the tablet from deep sleep the drive is not mounting and i have no music. After a reboot everything is working fine.

What are you guys thoughts on using an aftermarket receiver for the amp and Bluetooth communications in a tablet setup? I'm going to start on my project, but I can't find to many people that haven't gone full blown custom. I use hands-free talk too much and don't want to fool with it. not much luck that I've seen getting that going consistently with custom setups. I also have subs and don't want to mess with hum from cheap amps or components. It just seems like you connect to receiver aux input, and auto mute with blue tooth works , amp and other things work better with less complication? I have a Silverado and there's tons of room to mount a deck hidden below under the cup holders. Access will not be terrible if I have to reset.

I'm using the parrot 3200 for hands free. I use tablet talk as well so I can answer calls on the nexus. I have excellent sound quality. I'm using a clarion eq so I have control over my amps.

I've used some parrot stuff in the past. They worked ok back in the day, and that 3200 prolly works better than most because it's simple input, vs some of the new ones now. Problem is, a decent Bluetooth unit cost as much as another head unit that will auto connect, auto mute, etc. Tablet talk should work seamlessly with my nexii, and any off the shelf BT HU. I'm just thinking from scratch it will be easier and cheaper this way.

OP - not trying to jack your thread, still want input from guys like you and wasted for what you see as pros and cons to these setups.

I am just using a BT HU that I picked up off Craigslist for $40. I was going to try and do something custom, but in the end, it was cheaper to just use a BT HU.

So you use the aux in? Any major issues? Hum or connectivity?

I'm also set up similiarly... but can't get Tablet Talk to consistently answer the phone calls over the stereo. Is a DAC required to get call audio over the car speakers? I don't see anything in TT on either the phone or the tablet to do this. Is it the order of pairing? Sometimes it seems that TT can't find the phone over BT, or has a bad BT passkey. I usually have to unpair everything from settings, and try all over. I run RCA out of the N7 into ground loop isolator and then to an EQ, and on to the amps & speakers. Sound quality is great, want to add hands free as well maybe soon. I don't have any steering wheel controls today. Thinking Parrot mk9000i with the controls and small display.... do I have to use BT/DAC USB out instead of RCA? Is this what the Parrot essentially is in this case?

USB Backup Cam

Very nice installation.

I've made some similar one on my French car Citroën DS5, and have one question I still cannot solve. Don't know if you can help.
My installation is Nexus 7 2012 with Timur USB Rom + USB camera for rear view.

When I start the car, the tablet is going back from sleep mode and all the USB are also powered on the same time.
The consequence is few seconds after going back from standby, an autmoatic prompt appears asking if "USB Camera Pro" is the right application to launch as the USB camera is detected. If I click on 'ON' and choose by default, as soon as the tablet goes back from standby, the Camera app launches.
And I don't want this. I prefer being able to start the application manually.

Do you know if there is possibility to disable this?
Thank you for help.

That's an amazing project! Congrats!
I'm going to start next week buying all the necessary. I read that Timurs rom has been stopped from 2013, is there same other rom still supported?
Thanks in advance.

Thanks bud!! I'm probably not up to date but check out Autodroid. I tried that but was having issues with my flash drive syncing before I put my blazer in storage. Could have been something on my end tho

All the major players in the after market coming out with "android auto" compatible receivers. I have had fun with my project, but android built in to a radio that has all the hardware for radio and backup cameras is going to be a better solution. Software mods on a hardware that's made to work will be much easier and functional. You guys might want to check it out. These receivers are suppose to be out later this year.

Well that just has NO FUN written all over it. Just kidding man lol.
Their actually already out and have been for a couple years now. Fold out Android

Personally the only reason I would get that over doing it yourself is to skip modifying your vehicle that has a single din radio. Which is why I plan on buying the one above for my diesel in the future.

I'm not sure where you read that but I can guarantee you it's wrong. I am running the latest Timurs ROM kernel on my N7'13 running LP 5.02 he is very actively improving his kernel.

BTW... Mine is permanently installed in the head unit of a Ford F 350 diesel
