I had lots of problems with my Atom rig before. It was really annoying, even though I only used it for navigation, music and internet.
Now with my i5, its a total different world. Even though I now use much more USB devices.
It can still get tedious to get something to work at the first time, but it works now after youre done with that configuration.
Right now its as stable as a double DIN HU - I have very high standards in that matter.
Most problems are Software related anyway. I got rid of the buggy stuff and only use software that works well and is still being updated.
JoyCons support for example is just ******* awesome. I told him 2 problems I had and 1 feature I would like to see and a few weeks later everything was fixed and implemented.
Fantastic. Of course he got a good donation for that level of support. If everyone would have that level of support for their Car PC software, there would be much more Car PCs.
Oh yeah, I have one issue:
The M3-ATX's interference is just horrible. I REALLY wish they will make an updated version soon that doesnt produce so much interferences that any Car PC radio gets useless and even remote door lock controls sometimes wont work. I also dont really feel comfortable driving with such an interference-artillery, but there is no alternative for my uses.
