On reports such as:
android car unknown error
android car pairing failed
android car does not work with car
there often is:
combination of errors
unstable dongle / adapter
firmware or configuration conflict
In those cases technical diagnosis needed.
In practice, we see failures caused by:
cheap Android Auto dongles
universal retrofit modules
aftermarket interfaces without OEM integration
poor cabling or installation work
Then “re-pairing” usually does not help.
The system must then professionally measured Becoming.
Analyzing Android Auto failures takes time and requires:
measuring equipment
technical knowledge
system and CAN analysis
That's why we work with diagnostic fee of €82.50 per hour.
you pay only for the time required
we discuss findings and solutions in advance
repairs are always done by mutual agreement
That way you know exactly where you stand - transparently and professionally.
Send us:
