Dear Community, I ask myself after a week with the Garmin Nüvi 360 (which should be one of the best external Navis) if I should not invest the well 3000 Euro and have an RTI retrofitted. Professionally I need the Navi about 1-2x per week. After I first had an integrated Navi with my Z4 I am spoiled a bit above all: – if I drive into longer tunnels no external Navi continue to count, but always “…no reception…” – after I drive out of my garage (with tunnels about 1-2 minutes) it takes about 3 minutes until Garmin locates itself – no TMC (involving traffic messages…) – If I have switched on the radio, let me navigate and at the same time the phone people because we are hectic, if the systems are not coordinated with each other. After I have now for a week my xc90, almost 1000 km drive, this has happened to me already 3-4 times. If I have built in RTI, this would be a little coordinated So dear Community is worth it to your RTI to equip me with your Regardi?
