About the DDX9905S install, finally I got it right!!!
My car is the 2.0 Turbo Diesel, Longitude, had the uConnect 5in HU but no amp/sw, it did not came with the Beats system.
I guess thatīs the main reason it must use the OBDII connection, other users here seem to have the Beats integrated amp and subwoofer and maybe these ones donīt need the OBDII plugged to the Maestro harness.
So, now there is no odometer flashing and it looks almost perfect! I will not consider replacing the old HU back...
My only doubt now is how to adjust the units for metrics, since the Maestro unit allowed me to properly configure it to metrics but the dashboard on the Kenwood display keeps showing everything in US standards.
Anyway, Iīm still interested on the AlfaOBD software and cable adapters because I donīt plan to go back to the dealer once the warranty expires on August/19.
