My rule of thumb with updating.

Is it stable now?

Does it mess up any at all?

Is there some feature that I know the different firmware has that I just have to have?

If its a yes, no and no then it doesn't get updated.

It takes at least a no, yes and damn skippy to get me to update an android radio..


Its risky to start with because you may brick it during the update leaving it a paper weight.

But even if your ok going for it, with a car stereo you want STABLE. A wacky acting radio can ruin your driving experience beyond measure.


Best source for firmware updates if your determined to do it anyway is the xda forum site as mentioned.

I have one eonon that was turned from junk to a cool radio via an update. I never really found the other ones I have done to be as stable after the flashings.
