I've just bought a RCD310 HU to replace a temperamental Altea original HU (turns itself on during the night). I thought it would be a matter of just plug and play, but I've heard there could be gateway issues that might affect the use of this HU in my 2005 car (battery drain). Could anyone please advise on any other problems that might arise from me installing it, and, what else I might need to do to correctly install the HU in the car?
Thanks in advance.
Thanks in advance.
