Having just completed the installation after web forum assistance, I thought I'd share the experience. Here's the 'after' pic View attachment 36012 The unit was bought off eBay from a UK based firm, primarily for UK based support, which proved very useful in getting email support to my numerous questions. eBay link to current listing - AUTORADIO DVD/GPS/NAVI/IPOD/BLUETOOTH/RADIO/USB/SD/ANDROID 4.2.2 Player AUDI A3 | eBay This was chosen due to: android o/s, 1.6GHz, 8gb onboard flash memory, two micro SD slots, hidden front USB and rear USB and iPod on extension leads in glovebox. Plus usual multimedia spec. Key factor was compatibility with CoPilot GPS as I already bought the app/maps. The unit replaced a Concert II single CD Quadlock twin Fakra aerial, half amplified non BOSE rear speakers. Removal was easy. Fitting the Witson was a challenge overcome by the support from iceboxauto and this forum in particular. Issues: Nice box and packaging, but not for the model in the box. Fortunately, the unit I bought was in the 'old' box used. No installation instructions or aerial adapter, both supplied promptly by iceboxauto when queried. Bottom locking plate holes don't line up with the mechanism behind the fascia. Workaround in use, involving panel below. I not noticed, could have had unit stuck in dash. CoPilot not available via online unit access to Google Play but able to download on PC and install via USB. Quadlock connector supplied had no bottom white row of pins for rear speaker line out. Used Autoleads PC9-417 to rewire the supplied connector to reduce the connector overload and space issues behind unit. Rear speakers are fine but no ability to vary rear balance L+R. Autoleads line out converter levels a bit low for me so bought a variable Celsus LC2A to see if this can boost them a bit more, yet to fit. No dedicated remote wire for amp but power ant wire can be used for more than just the radio. Handbrake 'wire' just required grounding but had to ask iceboxauto. Not used rear camera or front cam input and haven't used the RCA outputs either. Now all resolved and very pleased with the performance. Not a simple plug and play option but also not the plug and pray experience it could have been. Bonus over factory options, no VCDS coding required. Thanks again to all the previous posts that helped resolve issues.
