I have an older model Garmin. I contacted Garmin to see if the data base could be upgraded to that of the RV specific Garmin. I was told it could not BUT Garmin would give a trade-in allowance on my older Garmin for the new RV Garmin. I think it was either a percentage or around $100 (I'll keep searching for that information).
