Point taken about ram usage, both OBD and Sat/Nav can be written within tight memory restraints but they would run much more efficiently with more memory buffers!

Being able to buffer more map data for example will vastly improve the route planning speed and ability!

To be honest it's not really an issue though because if it's technically a nightmare to add extra ram then it's not even worth considering!

I'll be watching both topics with interest and pleased to see any progress,

Anyway, thanks for your comments,
