Does anybody have any experience with Android radios? I was thinking about this one:

http://www.ebay.com/itm/Detachable-Tabl ... 1054507360

You get both a radio and a tablet, that work together as one unit and separately as a radio in the car and an Android tablet. I'm wondering if it has the guts to run CaniOn reliably. Also has capabilities for AV in, USB, and a rear camera.

I'm working on using my table AS my car stereo, gps and canion. Thus no problem with figuring out if it will work or not. I've even made my own docking station in the car, well working on the prototype now. Hopefully, I'll have it upholstered this weekend if I can square away a few more details.

Like the removable tablet radio idea, just a bit pricy for my budget right now. :D
I do wonder what version of Android is on that radio, it says 4.0. The current version is 4.4 and I'm learning this DOES make a big difference. I wish Android's were easier to upgrade and not have to root the system. I just don't understand why I can't totally screw up my own system if I want to. I come from the PC world where I can muck up things as I like.

I just don't understand why I can't totally screw up my own system if I want to. I come from the PC world where I can muck up things as I like.

I know, right? If you own the system, you should have full access to it.

My phone went from 4.1.2 to 4.3, and what a downgrade that was. Now AT&T is shoving another update down my throat, and the only way I've found to stop it is to go in and kill the process and service. Haven't played around with 4.4 (KitKat) yet. I'm old school Android and loved having search and menu buttons, not the action bar across the top, which is why I haven't moved up to the Galaxy S5.

I used to have my old Galaxy S phone set up on the dash to act as a carputer. Being 4-5 years old at least, I was running into battery and speed problems. The biggest thing was it couldn't hold a charge overnight due to a problem with the phone's memory requiring a keep alive app to keep the phone on. It took 3 minutes to startup, and then another minute before I could open CaniOn. By then, I was already 2 miles down the road.

My tablet is too big to use as the radio, but that thought has crossed my mind a few times in looking at these radios. Would you mind sharing pictures and more information of your upgrade?

PV1 - I'll post pictures here as I develop this idea.

The idea so far is:
I found a 12v to 5v power supply to keep the tablet juiced up. I'll splice this into the radio harness adapter. Using Tasker (an android app), I'll use that to power up/down depending on the power from the adapter.

Using the OTG (On the Go) USB port, I'll add in a USB hub so that I can add USB devices to the tablet. I'll use SDR and SDR Touch for the radio, the adapter will plug into the factory antenna using another adapter. The CanIon will be the Vehicle Reporting System and then later I'll add a GPS dongle to add GPS to the tablet.

That's about the most I'll expect out of the tablet is those three functions. I've already stripped the tablet way back and removed most of the internet stuff like the search bar from the interface, as I don't want to use this for any Internet purposes. I'll just use my Windows 8 phone for that.

I installed Nova Launcher 3.0.2 to set up the rest of the tablet, I didn't like how easy it was to move the icons around on the home page and I didn't need five side pages either. I'm down to two and plan to pair it back to just the one. I'm also able to lock the default page.

Now I just have to finish the box I'm making that will replace the radio. I've built it once out of cardboard to test my theory and get most of the dimensions. I built it again out of 1/8" mdf, but some of the dimensions are still not quite right. I'll build it again this weekend. Once that is perfect, then I'll upholster it. After that, I can start buying all of the adapters and parts I'll need.

Does anyone know if the stock radio in the base model (ES?) has an amplifier built in? I have found a small amplifier for a two channel setup that I can plug my audio port into. Just not sure if I'll need that if the car has one already. I'm thinking it doesn't as it's the base radio.

Like Dylan...I went electric.

Which SDR dongle are you going (or planning) to use? I'm glad that picking up radio without it being built into the device is now possible. Also, what tablet are you using?

I set my old phone up with Impel and Rotate (to force reverse landscape) so that it would unlock the phone, turn on Bluetooth, and open CaniOn when power was applied, and do the opposite when power was removed. I just used the USB port on the radio to power the phone, but obviously another source is needed if the Android device replaces the radio.

How are you planning to power the tablet and have a USB hub at the same time? From what I've read, you have to use a certain value resistor (which I can't remember the value) between the ground and sense pins to allow both OTG and charging. I believe there are Y cables that allow this.

Nova Launcher, by TeslaCoil Software 8-) . It must be good for it to wear the big T name. :lol: Actually, I just installed it on my Android VM (yes, a virtual machine on my laptop) and it is pretty slick. Maybe that will help make these forced updates less painful.

I had a chance to play around with that launcher some more. I don't think I'll use it on my main phone (I'm too used to Samsung's Touchwiz launcher), but I'd definitely use it on my other Androids.

The SDR Touch app is pretty neat, too. I'll have to get a tuner so I can listen to something other than iHeartRadio at work :lol:.

I wish you luck with this project. It sounds like it will turn out better than the Android radios currently available on the market.

Not to shoot a hole in your plans, but will the SDR Touch app continue playing sound in the background? That wouldn't be much fun if the radio gets cut off every time you minimize the app.

I use caniOn on a Nexus 7 1. gen, connected via cigarette ligther usb-adapter to charge the android device, if the car is "READY". I also use the caniOn setting "auto close" in alliance with app 'plug in launcher' to start/stop caniOn via ignition key. So i do not need to handle the android device/caniOn. It's on, when the car is "READY" and it's off, if the car is not "READY".

Regarding android car pc: i suspect it will not be fast enough to handle caniOn AND at least the radio-app. Also the display has only 800x480, so all the graphs will not look good for me - i recommend at least 1280x800, as known from Nexus 7 1. gen (all screenshots at https://play.google.com/store/apps/details?id=emobility.canion are done on a Nexus 7 1. gen).

Samsung Galaxy S2 has a 800x480 display.

These screenshots are from Samsung Galaxy S2:

PV1 Questions: Power, the tablet I have has a 2mm power adapter port separate from the USB OTG port. I'll be using a 12v to 5v power adapter that I'll splice into the radio harness adapter to get a keyed 12v power supply. The USB/OTG port will be solely used for the SDR and GPS dongle. Using dongles helps the tablet because the processing is off board not on board, I've read several articles where this is beneficial to use a GPS dongle versus the onboard GPS if your tablet is equipped with one.

My tablet is called a ValuePad VP-111K. I picked it up for like 60 bucks on Amazon, it has a Cortex A9 dual-core processor with 8gb of ram. It says it has the same GPU as the iPad and the Kindle. It seems to run okay, I have not had any problems with it in the month I've had it.

As far as Audio while switching to other apps, I'll see. Don't know how that goes but I'm sure I'll sort it out or just not care or build an overlay that will give me the stats I need while in the radio. Something will work, not sure yet. But thanks for letting me know some of these risks, I'm quite new to Android. I'm a solid PC guy - even look like one - bald, glasses, old - that's me. :lol:

me68 - I've been using the CanIon and the only screen I'm using is the TripTimer. When I'm driving I need quick reference numbers not graphs and charts. Those are too detailed to analyze while I'm on the road. I almost think it would be best to move the analysis to another application and offer a 'lite' interface that has just the basic numbers like Amps/Volts/Wh, etc in a large easy to read format. A clock would be nice as the clock in the notification bar is way too small and removing the radio I lose my clock.

Photos of my tablet dock. This is Model 2, the first design after the cardboard stage. I'm going to build it again this weekend. The sides are still too tall and don't go back far enough, causing the backrest to catch in the reclined position. The backrest needs to narrowed a bit to allow for the upholstery. The bottom board is perfect. It's ugly right now, but once I get it upholstered it should look a lot better. Notice the photo that I have the backrest open, you'll see the shelf in the back that I plan to install the amp, powered usb hub and power supply on to. It makes a perfect area for all of this and the backrest simply tilts forward for easy access. Surrounding this box will be a mask to hide the gaps in the sides and provide a 1" lip on the front to keep things from sliding off the shelf in front of the tablet. The shelf can hold my phone or other small items. I actually think this is a lot more useful than the OEM radio.

Bonjour,
About the use of an external USB GPS:

You will need a specific application for instance this one.

I have no ideas how canion will react with this setup...
I am waiting for your feedback.
