I have an A4 factory equiped with RNS-E.
I'm considering to install a track and trace device to log my trips.
Would it be possible to hook up this device to the same GPS antenna already installed? If yes, how?
Thanks te advise, Waterpetter
The GPS antenna is an active device (meaning it has to be supplied with power by the device it's connected to), so any splitter would have to include a DC path to supply power to the antenna when either the RNS-E or the logging device was on.
The big downside of sharing the GPS antenna is that most splitters are passive (i.e. they attenuate the RF signal) and since the signal from the GPS satellites is very weak that's not a good idea.
