A word of warning!
My RCH+ stopped working today. Also, the power/lighter socket, while working, was unable to power and charge my mobile phone. It was only when I got home and came to find my phone completely discharged that I linked the two facts.
I've emailed gap-tech for advice. However, I suspect that the unit has failed, possibly blowing the fuse (not had chance to check that out yet). The power socket I suspect os sinking power through the gap-tech device rather than from its 12V supply.
While it was a doddle to fit, I suspect it will be a bigger problem to remove, especially with a view to replacing it. 5 connectors were hard enough to accommodate in the small space, but adding more will be a nightmare!
Anybody else used this and had similar problems?
