Yeah I know what you mean about roundabouts... The IGO is really bad at updating quickly enough at roundabouts so it's not always clear which exit to take as the map sometimes hasn't caught up with the actual position of the car! I'm not sure I can be bothered to route the unit as it's too slow. I have used APK files before now side loaded, and that gets around the android version and tablet problem for some apps, but again a painful experience... I'm using a Garmin in the corner of the windscreen like you know for long journeys for the very same reasons.
Hi @@frankiep, on the other side you should have the fog light, I don't encourage you to replace it with a reverse light as the rear fog light is road requirement in many countries. I'd follow @@Andrewgrale's suggestion. What I use are the led number plate lights, just so you make sure are waterproof. Hope it helps.
