Re: How do I update my garmin navagation sys.
From the reading I've done about factory built in nav units, the updates are usually around two years apart, and cost around $150 across most manufacturers. I knew this going in when I bought my '14 JGC. It's the first vehicle I've owned with a built in nav. I've been using a Garmin with lifetime updates for years. I really like the convenience and ease of use with the built in unit, but there are trade offs.
Mine: 2014 Overland 4x4 V6, ORA II, billet silver/black, Michelin LTX M/S 2's, MaxCare Lifetime, delivered 4-13-'13
Wife's Jeep: 2008 Compass Sport 4x4, 2.4L I4 DOHC, CVT, Lifetime powertrain warranty
