Ok so i saw that unit that someone sold for £450 on here and brought me one soon as i could. Installed it last night after finding a few guides how to take the old rdc 500 out and followed them no probs, was all good!! had to adjust the position of the gps antenna a bit to get a better signal and it works great!! but today the unit has been turning itself off and restarting

so i did some more research on the wonderful interweb!! but to no avail so i just took it back out and im goin to send it back and get a refund/exchange. its not that much hassle to change the unit but dhl is a whole new kettle!!
