After 15 days without RTL Trap my Unit started misbehaving again with 5.70, RTL Trap, Data exception Error, Abnormal Powerdown. I went back to 5.10.
The 5.10 firmware works fine with Modified Splash for 5.70 as supplied by Lolypop000.
Conclusion 5.70 Sucks on a Nuvi 1300. Maybe Garmin wants customers to buy new nuvi for XMAS by supplying faulty firmware.
Every Firmware after 5.10 is faulty to a degree. What's up Garmin ?
