PowerAmp is an application you can use to enhance sound quality, It is like the media player software that comes with the radio but much better. I red in other forum that Viper4android makes little difference, I don’t know if Leshkin has tested both applications.
I've found viper hasn't done anything - i may not have it configured right though.
Poweramp sounds better than native music app. but poweramp is no good for listening to DAB/FM, spotify, movies, etc.
Good to know you're happy with the unit, so thanks for your feedback mate. Have your tried a PAC SNI35 or PC1-601 Line Converter yet to see if that sorts out the rear speaker issue? Also, would you mind sending me a link to the USB camera you bought please? I've had a google but they're either too short or expensive in the UK compared to what you've found.
I'm also going to get a ELM327 OBD2 Bluetooth Scan Tool as it looks like a neat feature to have and for only a tenner as well.
Ah yeah, my ELM327 dongle works well with Torque Pro too. Can connect to both ELM327 and my phone via bluetooth at the same time which is handy.
Not tried a line converter yet - haven't decided which one is best - since my HU already came with a bose loom so m 4 x speaker outputs are already phono - so think i'll need the PAC SNI35.

The picture quality is good enough, but it seems to struggle when the sky is bright, it makes everything else look dark. will probably upgrade in the future but does me for now. The head unit picked it up with no setup needed, and as long as it was recording when you turn the car off it will automatically start recording again next time.
