While searching for a sync2 to sync3 upgrade to my 13’ Ford F-350, I came across the intelligent1tech website. I compared their prices with others on the internet and found their product to be well under the cost of most other retailers. The product was as advertised, with simple installation and works great. The only insight I would give to the seller is to allow more time on your return policy (60 days instead of 30) since shipping is coming from overseas. If there would happen to be an issue with the unit, it leaves very little time for the buyer to return. Otherwise, I am very pleased with the purchase and performance of this unit.
