Streak, sorry to [sort of] hijack your thread, but talking about GPS systems on the bike, I have just ordered myself a new TomTom Urban Rider (found out I had enough points on my Amex card to get one for just $184, thanks ex Mr employer for paying my bills!).
I do notice that the one gripe that people have is that the charging USB connector is underneath a little door in the bottom of the unit that you can't actually have open in the normal mount. This means that you can't charge the thing whilst you're on the move. You can buy a mount that does allow charging, but it costs $159!.
I have seen a review on YouTube where the bloke modified the supplied mount by cutting a slot in the bottom to allow the door to be opened when fitted.
So my question is, has anyone got one of these, and have they done the mod, and if so does it significantly weaken the supplied mount in any way?. In other words, does the mount still work with this slot cut in the bottom???
