My Garmin 2598 GPS let me down

 

I just did a trip from Surfside Beach SC to Gulfport MS. Trip down was great, no problems. Trip back not so good. In Lexington SC it took me off of I-20 on to side street and country roads. Finally took me back to I-20 but cost about 15 minutes. Going down 501 near Conway SC it wanted me to go down 501 business through downtown instead of staying on bypass 501. I didn't fall for that one. I checked and the GPS is still set for fastest route. It didn't try to take any of these off interstate routes going to Gulfport. Strange, it also tried to take me off of I-85 to I-285 in Atlanta again on side streets again but didn't go for it that time either. Anybody running into this with the latest map update?

My biggest complaint...

My biggest complaint about my Garmin Nuvi 3590 lately is it will route me perfectly to a location...and then route me a totally different way back home in which it will do as you describe and take some weird side roads which usually adds several minutes to the trip. It happens about 20% of the time. Now I double and triple check the route back home before proceeding.
