Our Philippine client told us the Internal GPS signal not good when he installed the last shipment which bought from 2021.

Now we told him our company has developed another type External GPS antenna HDD MDVR ,has very better GPS signal when the truck run outside .

Because the HDD type MDVR has magnet ,so it will interfere the MDVR’s GPS singal ,because both of them are in-built structure. Now ,our team put the GPS module outside ,through RS232 IO port to connect the extenal GPS antenna .
