I'm 90% sure I saw this on eBay the other week! exact same photo.
Was being sold by a breaker.
it is still on ebay
and the one on gumtree is the same picture for sure
vauxhall astra j ,gtc , Sat Nav Unit., Nav 600 | eBay
so if it is not the same seller i would not trust it as he can not supply a picture of the item he is selling
unless you pick it up.
but that one on eBay is cheep and Andy will do the retro fit for £180
if you supply your own unit
but you would still need to buy the storage tray for the USB
and supply your own antenna
so you are looking at £430 to get that done that is cheep
and when that one on ebay has gone it is going to be hard to find one at that price
Must be fake. One is Nottingham and the other is Birmingham
i would not go any were near it ether
yeh seems abit strange, a little too good to be true...
