Hello together, after a V40 and now a V70 I would like to order a new XC90 on Thursday. As far as motorization, color etc. I have set myself so far, the only problem is – do I now order the Navi with or not ? I actually know the majority of the travelled routes, on the other hand I wonder if it is not “standard” to equip a vehicle of this (price) class also with such a system, also with regard to a later resale value ? Often enough actually in case of cases also a mobile navigation system like tomtom & Co. How did you handle any tips and opinions ? Am there at the moment quite undecided …. Many greetings Marco
