You also said the maps are on an SD card
Does the car unit take an sd card?
Ok Lets try and clear up a few misunderstood remarks (which if they came from me would not surprise me!!)
I also saw that IGO recommend USB, but that in a way that was what started this post ,as I got nowhere with USB,so I went back to IGO and they suggested as I quoted above
If you note their advice its to use USB to install via Android file manager, which I do NOT have installed, hence my reason for need to find a way to install APK files from my laptop, to car android device? Again as stated I do have all necessary APK files in place on my laptop. It has to be the laptop, as I would have a job taking the desktop out to the car!!!!!
(Advice on how to install via USB please) Somebody mentioned USB and I replied I had a full USB connection available.
I did NOT get the maps from playstore I downloaded the APK files (among them the APK file manager) from Google android play store.
The car has a dedicated GPS Satnav mini sd slot, which I thought I had made clear? As I said, I have a fully loaded mini sd card with a reasonably expensive IGO sat system, which all of a sudden my car media system will not install???
As soon as I insert the card in the GPS slot, the card shows as Sat Nav GPS mounted. It also shows in internal storage but I cannot activate it?
I also have second dedicated sd slot for media sd card which works fine.In fact there isn't much this system cannot do (except for reloading my sat nav)
Plus lets remember this card was in place and sat nav running beautifully, until I removed it to do IGO updates??
I'm aware of the Rover 75 video,but its very dated, if you look carefully you can see that, post service support was almost non existent, I have yet to come across a 75 fitted with it, it was special order and an add on, it was included among some of the very early builds in the Connesiour SE series.
What is the date of the release of that video please?
Most Rover owners who require installed sat nav, opt for the BMW E46 for which the car is fully wired up. Its a straight forward plug and play.
