I think you need to find a car with Professional multimedia rather than standard Business Nav
Don't think bus Nav can be upgraded with rtti .. that comes with tmc
Pro Nav comes with rtti as standard .. free for the first three years then about £200 pa to continue it
Tbf .. it not as good as waze
My 09 E90 had it .. so it was around then
I've just renewed RTTI in my 13 plate and it was in the region of £35 for the year. The pricing is all available in BMW Connected Drive. If you have the VIN number, it will give you the pricing:
