First of all, we, RSNAV team, thank you for your interest and business with us. The numbers of inquiries and expressed trusts on our products are somewhat overwhelming but we are not handling it in a reasonable time frame(48 hours). Currently, our e-mail response time is prolonged and average waiting time for an answer is 3~5 business days.

If your answers are not answered in 3~5 business days, don't hesitate to call us within the consultation hours prescribed in the contact us page. Oddly, a good number of e-mails are simply ends up in spams or just vaporizing. Especially when the inquiry contains some transaction relate words. Our primary e-mail service is Gmail and all the e-mails are then carbon copied to our teammates to their e-mail addresses but it seems multiple spam filters and blockers are redundantly working and causing some e-mails to be marooned.

We eager to restructure our client service group and reorganize our e-mail system within next 6 months.

RSNAV.com is operated by a very small team of dedicated staff. Despite our small team, we are in the process of growing our team to be able to help you quicker and more efficiently. Due to the popularity of our products we are experiencing a growth that is proving challenging to keep up with. Please be patient as we grow to better server you in the future.

We highly recommend joining the RSNAV group in Facebook, where Daniel monitors posts and questions on a frequent basis, even when outside of his office. Being a user community, there are also a growing number of RSNAV users that are very eager to help others.

Do not message Daniel or the RSNAV page using Facebook Messenger. It is NOT monitored and questions posted through messenger will not be read or answered. Please refer to the Contact Us page for the most appropriate email address to send your questions to.

Thank you, the RSNAV team.

Except the standalone interface line product, from the date you place an order to the delivery to your doorstep would take up to A MONTH for All Android system products. This is due to forementioned LCD and IC shortages at the industry. This situation is likely continue until late 2022.  

At this time, the average waiting period with DHL is between 7 to 14 days. This means that for at least 7 business days your tracking number will be shown as 'Not yet picked up'. This is beyond our control, until such time as the worldwide shipping companies are able to increase their capacity.
