Sat Nav Upgrade on L322

Anybody ever done an upgrade? Is it possible?

My 2004 is a little dated now.

Depends what sat nav you already have. You can upgrade to the later Mk IV sat nav system (as your entire nav system is from BMW) This replaces the nav computer in the boot LHS, ( the bit you put the disc into)
New computer is approx 400 quid. Gives you post code search, as well as 3d view fo route and split screen option ( route on one side, computer on the other)

You cant upgrade to the later touch screen system.


Why get a BMW Navigation Computer version MKIV - Bimmernav BMW Upgrades
