Thread: Cake and eat it too, GPS tablets

I tried to work this out and came to a dead end. Tyre monitoring was on my wish list too. One challenge, and please correct me, is Blue tooth only supports one channel or connection at a time.

I don't think this bit is correct. I link to my external Bluetooth GPS unit and my Bluetooth stereo unit at the same time - receive the GPS signal as well as send music to the head unit.

I have a Galaxy Note 10.1 for this (not the 2014 version, unfortunately). I must investigate camera-in for a reversing camera...

The other thing is wireless reversing cameras do not use wifi but generic 2.4ghz, so again can't link those to a tablet

That wouldn't bother me if I cant run Torque app and phone call at same time

From what I understand, a bluetooth smartphone/tablet/PC can pair with up to 7 devices at once - but only have one connection per purpose at a time. So one bluetooth phone connection, one bluetooth audio (A2DP) connection, etc.

I've thought about this too, and I believe the problem can only be solved with a specially developed app.

You see. For the reversing display to be useful, it must display only when reversing, and then switch back to whatever was showing beforehand. This requires a signal from the car, either a reversing signal from the Canbus, a signal from the reverse light, or worse case, the rear cameras transmitter powered by the reverse light. It requires a special app that displays the video image when the signal is present and then goes to sleep handing back the tablet display to whatever was showing before when the signal is absent. If you don't have this, then you don't have a practical reversing camera system. As far as I know, no app developer has gone to the trouble of developing this.

The closest thing I've seen to this is the dedicated Parrot Asteroid Smart tablet which is a combination Nav, reversing camera, Sound System, and is Android app friendly and therefore supports a range of mapping apps, but not Hema, I believe.

Thing is none of the ebay cheapies have bluetooth, and none of the proper tablets have av-in.

Saw this a while ago. Maybe gives you some ideas about the need to have AV in on a high quality tablet. Whether it is really a viable solution is something I can't say but it is interesting.
